WIBTA: Should I confront him?

‼️BACKGROUND‼️ My boyfriend M19 and I F20 have been together since October 2024 but broke up briefly in the end of march 2025 and got back together in the end of may 2025. The relationship ended because of a lot of horrible communication and outside influences. I found he was talking to a lot of girls before we broke up the first time 2 times and the first time we came to an agreement that if I found it again we were over. Well I found it the second time and full on freaked out at him, told his mom and he, in the end, broke up with me because he felt I was too controlling because I asked him not to talk to any girls he has previously liked, hooked up with and any old talking stages. His mom and I get along very well and even after we broke up we still hung out and he even gave me the okay to go to his 19th birthday party. During his birthday party he brought a girl with that he constantly reassured that was “only a friend” and I knew I shouldn’t believe him but I did because I was in love with him. Anyways, during the few months we weren’t together I found out I was pregnant and miscarried at about 7-8 weeks. I did everything I could to get over him and move on with my life. I didn’t tell him that I had a miscarriage because he was worried I was going to “baby trap” him eventually and I didn’t want to add that stress to myself. The middle of may he messaged me and wanted to hang out and talk, I continuously told him no and to leave me alone because I didn’t want to get hurt again. One of the times he texted me, he flat out said that he only missed the sex and couldn’t get any from anyone’s else. Eventually he wore me down and I caved to a date/ another hang out but it still hasn’t happened. He did very well for a while when we officially got back together but it slowly went back to last time and he does catch himself and correct himself sometimes.

‼️THIS IS WHERE I NEED HELP‼️ I am a little over 11 weeks pregnant with his baby(it was an accident) as soon as I told my parents they kicked me out so I moved in with him and his parents

Now this is where I need help… the girl he told me was “only just a friend” I watched him block her on every single thing they had each other on and he promised me he will never talk to her again. Last night I couldn’t sleep,and I was overthinking because he’s been acting weird and went through his phone. I found out she is not blocked on Snapchat and was popping up on his quick add. I blocked her again but I cannot stop thinking that he is talking to her again and hiding it by just deleting her when he goes to bed. Should I confront ask about it when I know that he will aft out and try to make it my fault again?
