not sure where we're going

My fiance and I are now 8 weeks into term. we haven't had sex in 6. this wouldn't exactly be an issue but I'm starting to realize the glaring issues with the relationship even more now. not to mention that I've been working 2 jobs plus taking night courses. She's incredibly cold. we never cuddle, rarely kiss, if I say I love you I basically have to tell her to say it back, she snaps at damn near everything I say, she's essentially the total opposite of who she was when we met. She even jokes about the fact that she is different now by saying she had to hook me somehow. I'm slowly seeing less and less of any reason to stay. I fell in love with a lie. all I want is for what we had to come back. i couldn't imagine life without her and her beautiful daughter, but it's getting harder and harder to imagine a HAPPY life with her. I should emphasize it was this way before the pregnancy I just kept lying to myself about it and choosing not to see it.
