I don't know who he is anymore

I love him I truly do.... but I feel like I'm sofficating.... I feel like I'm drowning in my relationship. He thinks I'm always wrong, picks out my appearance, hates on my family.... tells me I'm always doing something wrong or I look bad etc. He never thinks he's wrong when I try to confront him, he never thinks he's doing anything wrong. And tonight I have had enough of feeling worthless, useless, unloved, etc. I try so hard with him, our little family. He never seems to care. We are engaged and have a 6 week old. He never pays attention to me, he doesn't try or touch me, he never seems to love me anymore.... I'm so sick to my stomach it's turning, I'm crying I feel like my heart is firing, I'm completely sofficating.... I feel horrible. I feel like someone is choking me and my heart is so broken. My stomach is tied in knots and I don't know what to do. I made him sleep on he couch so I didn't have to hear how horrible I am.
