Why did I marry my husband?!

I fucking hate him! We’ve been married 3 years now, have a toddler and another on the way. He treats me like fucking shit. Yeah sure he’ll do nice things for me but seriously the way he talks to me and the way he raises his voice to me and calls me names I’m just so fucking sick of it. I just flipped the fuck out right now like full on lost it. Threw shit at him and it was bad. That’s the first time I’ve ever lost it with my son around but he fucking just pushed and pushed and pushed and I couldn’t take it anymore. He started calling me dramatic prior to me losing it yet he was the one completely being Immature and dramatic to begin with I was mocking him which then made me “dramatic” I feel bad ONLY because my son was scared. Ugh I shouldn’t ever married this piece of shot and now I feel completely stuck. Wtf do I even do?! Pregnant and with a toddler! Ugh I don’t ever want to lose it again like this in front of my son. It’s usually my husband that loses his mind and doesn’t care that my sons in the room. I can’t believe I just did that. 😭😭😭😭
