Are you really gonna change...?

How do you know if someone truly, genuinely means what they say?

I’m married, I’ve been married since May and I just found out recently we’re expecting our first baby together (I have a 2 1/2 year old from a past relationship)

He’s not horrible to me by any means, but there are some issues that really need fixed for our relationship to be happy and to thrive. My relationship with my sons dad was horrible, he was verbally abusive, cheated on me with tons of girls even when I was pregnant and when we had a newborn. He always promised to change and begged me to stay with him and I did for 2 years. But nothing ever changed, it only got worse.

It’s hard not to be scared because of that relationship honestly. My husband has never cheated on me, and I know that. But I do worry sometimes he’ll meet someone better. He’s only lied to me a couple times about stupid things like smoking cigarettes behind my back after he quit and calling into work. But with my trust issues it made me paranoid.

He’s got anger issues, he would never hit me but he can snap at me sometimes and it’s upsetting. Also lately he’s not been helping me around the house at all. I’ll ask him to do something for me and he says yeah but never does it. Which is especially hard with all these pregnancy symptoms going on. He just doesn’t put me first, he’d rather play Xbox or sit on his phone. I feel like he doesn’t put effort in 75% of the time. He promises he’s gonna do better and work on it and doesn’t.

What should I do?
