22, 2 babies and just ended our relationship

Idk if im making the best choice. Im kinda stuck. But what do you do when you feel like you are locked up all the time.

I wanna be happy i want my SO to want to do things with me. Take me out with him.

We had our first child 3 years ago and im currently 34 weeks and last night i had enough. He went out and didnt come home till 4 this morning. Like really.

I said i was done. I keep going back and forth in my head but. Its like idk what to do. Kick him out? Try again? End it all ughhh i was never this emotional with my first.
