What do I do?

I had a baby 3 months ago, my husband kinda helps me with the baby. In the past 4 days he’s changed 2 diapers. And he hasn’t fed him a bottle in two weeks. Him helping with the baby isn’t what I’m having a problem with. I’m totally fine with doing all the work. What I’m having a problem with is my husband swears up and down that he doesn’t watch porn (we haven’t had sex in weeks) but I walked in on him watching porn tonight. I ask why he was watching it when all he had to do was ask me for sex, he says he would rather have a girl without stretch marks and without the extra “baby” weight. I of course have been struggling with the way I look since having my baby. But now this, that comment he mad hurt so bad!

What the hell do I do.
