Husband problems?

i dont know if it's just a phase or if something's wrong with me. hopefully someone can relate. My husband and 1 have been married 2.5 years. I don't care for sex (for a long time now) and I dont want his babies, or anyones. We are experiencing a bit of Stress at work, but when we get home, we dont really talk. instead we just sit on the couches and ignore each other. we are more like roommates than married people. sometimes I give in to sex, cause he irritates me so much to get some. but I honestly don't care for it. And I don't want his, or anyone's children. And he's been hinting for children, alot. am I in the wrong? Have we outgrown each other? EDIT: We had the baby convo before we got married. We had set our values and needs before tying the knot so we know what the other want. we both changed since then. i do love him, dont get me wrong. but I just needed someone who's gone through something similar.
