A good marriage is not something we know how to have by instinct. It can take a great deal of effort and sometimes we have to learn new things to get it to work the way it should.
It's sad that you don't think that you can stay married to your husband and have your own life at the same time. It's quite possible that is true, but have you at least tried to go to counseling to save your marriage first? When we're in a place where everything seems dark, it's very hard to objectively see what part we play in our current situation. Having a "mediator", or someone not connected to either party emotionally, can help you learn how to make your marriage better. Even if your husband won't go, you can make significant improvements in your life by going on your own.
It's quite possible after going to a counselor you find that a good marriage with your current husband isn't going to be a reality, but, in good conscience, and for your child, you should exhaust every possible effort to make sure your marriage is not salvageable before you take that fork in the road.
I personally feel my marriage is the most important aspect of my life besides my relationship with God. My relationship with my husband affects everything about me. It affects my kids, my work, my relationships with others, and even how I see myself. My marriage doesn't define who I am, but it can definitely affect how I define myself. I put into my marriage exactly what I think it is worth, which is everything. There is no amount of money I wouldn't spend nor amount of effort I wouldn't expend to save my marriage if the time came to make that choice. Now, I know there are always going to be situations where no amount of counseling or extra work can save a marriage if both people aren't committed to it, but before you make that call, my advice is to make absolutely sure you do everything you can before you throw your marriage away.
Many people are so quick to give up on a "bad" marriage because it's easy, and let's face it, we're a society of very self-absorbed people. We tend to believe our happiness is the bottom line. But you have a child this will affect, and if there is any way for you to be happy in your marriage, you should try to do that before you give up.
I was just about at my wits end shortly after I was married to my husband and broke down and went to a marriage counselor. My husband also agreed to go and after about a year, we were able to learn some new techniques on how to deal with our differences and gain a better understanding of our relationship and we've now been married 15 1/2 years and going stronger than ever.
It's true that you cannot change another person, so if you're husband does not want your marriage to get better, you may decide it's best to leave in the end. But on the slim chance that counseling could help your situation, particularly knowing it will at the very least help you get into a better place emotionally, please try it first.
Blessings,
