Relationship issues

Yesterday, my boyfriend & I got in a fight because I caught him looking at inappropriate videos. We had just got in an argument about this last month and he swore he would stop. He told me that he didn’t do it and was basically gaslighting me so I told him I wasn’t in the mood to argue about it anymore and that he could do whatever he wants because I’m done trying. We haven’t talked since yesterday and even slept apart..I’m 7 months pregnant with his baby and I just can’t stop crying. This isn’t the only thing he’s done, I caught him sexting with a woman back in January. I just feel so dumb I know I should’ve left way back but now I feel stuck because we have a child on the way.

I was explaining to him that this is hurting me and all the things he’s done and he straight up told me “Well you’re the one who forced this relationship not me” I told him how did I force it?? He would give me a bunch of mixed signals. He told me he didn’t want to date but he wanted to meet my family. He told me he didn’t want anything serious but he would invite me over and tell me he loved me. I had enough one day and asked “What are we? I’m confused about where we stand” he didn’t answer so I told him i didn’t like all the mixed signals and I wanted out of whatever this was. He begged me not to and said “Okay let’s date then” After that, we just had the title but he was never fully committed to me. He would flirt all the time with girls online and I stayed because I really had feelings for him and I thought that he would change once he seen how good of a partner I am. He swears that after January, he is fully committed and he is trying his best because he “loves” me but when he told me I forced it yesterday it just made me feel really bad. 🫤
