I need relationship advice

[3snakes]

My significant other and I conceived a child after dating for a month and a half. We've now been together for 12 years and are not married. As of right now, I am debating whether or not to leave this relationship. We are more like roomates than anything else. We sleep separately and he refuses to sleep in the bed with me. There doens't seem to be any affection and very little sex. I have waited for him to initiate sex with me and ended up waiting for over 3 months, finally got fed up and initiated it with him. There isn't another woman, he says he's just not interested in sex. I can't get him to do anything around the house, and most of the time feel like I'm there to serve him. I crave intimacy and affection from the person I have spent 12 years of my life with and told him so. Nothing has changed since then.We basically lead separate lives and we share very few similar interests. I'm not sure at this point if I love him or not. The utter lack of sex, affection and communication is leaving me feel very alone. He is a good person and if I could get these things I need in the relationship, I would not be questioning the relationship. How do I get him to open up to me? I've tried numerouls times to talk about these things and he acts as if there's nothing wrong. What should I do?

I agree with the previous poster.

The fact that you have been together for 12 years and not married kind of says that you are not really committed anyway.  Perhaps it is time to move on.  Just make sure to make it amicable for your child's sake.
