I wish I could end the pain

I’m currently four months pregnant by a serial cheater. It’s not our first child together. I should’ve learned my lesson when he cheated my first pregnancy. I broke things off with him in August. He says he wants to be with me but I told him to earn it. Which he hasn’t. He’s still cheating. He did a romantic beach date for the other girl , I haven’t gotten flowers in over a year. And now he’s going to vegas with her while I’m fucking pregnant. I want to end it all just to cause him pain , for him to feel half of the shit he’s put me through so he knows he’s a shit person, I’m so tired of everything. I’m tired of being alone and going thru this alone. I want my life to be over already, I’m done I’m fucking done
