There is nothing in the pregnancy books that tell you how life will be after you have your child. It only tells you how to care for your child. Nothing states in a book what women go through once their title changes to "mom".
A lot men have no idea how our roles in life change once we become mothers of a child(ren). We have so many responsibilities to uphold that over time, we feel our lives are blah and just so routine. We as women tend to loose ourselves in this new found role.
It is VERY important that in any relationship that your partner, be your friend and your teammate. Your spouse should help take half of your responsibilities off of your shoulders. This will hopefully allow you to have some guilt free time to yourself. Plus appreciate your spouse more and respark that feeling you have for him.
Also no one ever tells you in these books today that when your child arrives, its impossible to give all your love and attention to your spouse. Men unfortunately do get the back burner when a child is born. Hopefully he is understanding, takes charge, doesn't blame and is a super dad and helps out as much as he can. They need to realize the little things matter a lot to us when we are being pulled in 10 different directions.
More importantly he needs to assist you in childcare to allow you some me time away from your daily responsibilities. This will allow you to recharge your self and hopefully start feeling better about yourself in all.
I was so overwhelmed being mom, wife, friend, lover....it also didnt help that my partner wasnt my partner during my pregnancy and after we had our child. I pretty much was on my own caring for our son. Only having support of my family. This in the end did create us to separate. I didn't know how to give more than what I was giving to my son. He required 100% of me, my love, my attention, my care, my support, my ability to teach, etc. Knowing my partner had a child before that he would understand how to help out and be a father...unfortunately that was not the case in my situation.
Be open with your husband, as you are. Communicate to him how you feel and how he can help you out. Get a hobby and do something for you. When my horse was moved out to pasture and my son was born, he was all I had. Until recently, I relocated my horse back home. Thank god I did that. It is so nice to have my own thing back. Where I am the second happiest...i can do what I love, besides being a mom. It recharges my soul, love, heart, mind and energy having ME time. Yes, sometimes my son is with me but I want to share this with him, at times, not always. As my horse will someday be his, hopefully!
Good luck and remember you are NOT alone. Truly feel every woman goes through this. But no one ever tells us this BEFORE we have a child and what to expect once our child is born how much it will affect our relationship with friends, family and our partner. A lot of divorces happen once a child is in the picture. Men do not know how to accept being #3 in their marriage/relationship.
