C.,
The first thing that needs to be addressed is that you say you are unhappy. One of the lies that many women believe is that we are owed happiness and somehow, someone else must provide it. This is impossible. There is not a human being alive that can make another person happy. Happiness comes from within. It is a lifelong choice. You wake up everyday and choose to be happy regardless of your circumstances.
Not only is it not owed to us, but it is not always good for us. If we were always happy, what then would we ever need to learn? At your age, you still have many things to learn in life, so you will have many times of not being happy. Give yourself permission to not feel happy. It's ok. And, it's good for you to not always be happy.
Next, you say that for 2 years, it's been a struggle, well then, you're just getting started. Marriage is a struggle, no matter who you're married to. You can opt out and re-marry, but then you just drag issues from your first marriage into your second and this is in addition to the new ones that you will have, and you WILL have them. So then, you now have past and present issues. Will you then give up so easily again in search for that perfect husband that only exists in fairy tales? Life is a struggle and you can either quit and give up on things or choose to live it to the fullest. The same goes with ANY relationship there is, it is a struggle and you can either give up when it gets tough or choose to put 100% into it everyday and know that you have done your part.
You say you've done all you can for your marriage. In 2 years, are you serious? Maybe in 20 years, you've done all you can, but you are just getting started and you have definately not done EVERYTHING you can do. Have you asked your husband how you can love him better each day? Have you asked him what you can do to improve as a wife? Are you afraid of what you might hear? Have you paid him 5 sincere compliments to every 1 criticism? Have you made a list of the top ten things that your husband desires from you and made it a point to meet as many as you can throughout the week? Have you listened to how he feels loved by you and made certain to do those things daily? What does he ask for or complain about most? He is telling you how to love him when he does this.
Next, you say you LOVE your husband. Love is a choice, not a feeling. Lust, infatuation, those are feelings, but love is a choice that you make after all of the "feelings" die down and reality sets in. Love is to: Listen attentively, Overlook often, Value highly, and Encourage regularly. Are you doing those things daily? If not, then you are not truly loving him.
When your husbands mother died, a part of him died too. You will not fully understand that until it happens to you. Since this happened while you were already having issues, he may have felt that he could not turn to you for emotional support. That means he may have unresolved issues about his moms death and about you not completely being there for him. He is probably also struggling with the fact that his daughter will never know his mother. If he was very close to her, he will be grieving for a very long time. It doesn't get easier, it just gets more bearable. Everyone has a different way of grieving and you will need to try to understand his way.
You say that you are trying so hard to keep everything together, but you don't have to do that. What you should be trying so hard to do is to just love your husband. You can't possibly hold everything together and you will wear yourself out trying, not to mention that you will frustrate everyone in the meantime. Just love him the way he wants to be loved and let God do the rest. Try going one month without criticizing him at all. It will get easier each week. See how his heart changes when that month is up. You will see a new man. Also, if you really want a great husband, tell him ALL the things that he does right! Even down to taking out the trash. Just fill him up with lots of praise. I'm telling you, you will see a new man!
Your husband is right to say that every relationship has problems. He has a more realistic view than you do. But, until he sees you rising above the problems and making sacrifices for the good of the family (without pridefulness), he will not see a need to put effort in, because he already feels defeated.
If you feel you are in 2 different relationships, than you are the one who has created the other one. You have to give it up and join him in his, afterall, you were created to be HIS helper, and to respond to him as a support system. Can he accuse you of being a very supportive wife? I hope so.
At 25, it is difficult to have health problems and he may not quite understand that if he has had none, the same way you may not understand his grief. That's why you may need to focus more on listening to each other without interrupting and giving advice. Let him know how he can help you out when you are in pain from your injuries. But don't nag, just sit down quietly and explain. Treat him like he is your best friend. Give him respect and honor him by asking his opinion often. Value and seriously consider his advice and then follow up and let him know how he has helped you. You are his partner and as a partner, you look out for each other, you bare each others burdens and you tenderly care for each other.
You say you think you need space. That is a way to manipulate the situation to your satisfaction. It's really like saying, "I'm not getting what I want, so I am going to punish you!" Please don't be childish. You are an adult and you are a married adult. You have to put away childish games. A marriage is a lifelong committment and it is not to be given up on so easily or so quickly. A husband is only as good as his wife treats him. Think about that. If you are loving him and helping him to be the man that he should be, he will become that man.
You say you hate to do this to your daughter, then don't. Make a choice not to, because she WILL suffer greatly for it. Sure she'll bounce back, but not without many scars. She needs not only to have both parents raising her together, but to see them love each other unconditionally.
You say that you've always said that you will not stay in a relationship for a child because you think it will not help you or the child, but who lied to you about that? Someone lied when they told you that. You and your child would greatly benefit from staying in your marriage (marriage is not just any old relationship, it is a lifelong choice to be one with another person as long as you both shall live). You would benefit by showing your daughter that when you commit to something, you never give up or quit. You would show her that although life is hard, you make a choice to live it regardless of your circumstances. You would learn that trials are to be walked through, not around. Your character will be strengthened and refined and made wise through every trial that you face and the next one, and there will be a next one, with your husband will be a little easier.
I wish I could sit down with you and walk you through this, but you have to make up your mind that you choose life with your husband and that divorce and separation are not an option.
God Bless You!
