Please help! I need your opinions!!

I’m 18 years old. Somewhere in July, I ran away with my boyfriend and during that period I found that out I was pregnant. We came to agreement to have a abortion. His family and my family got into feud, and my family desperately tried getting me back, by lying about loads of stuff and making up scenarios.

Nonetheless, I came back and one that very same day, I got in touch with my boyfriends ex. Now let me start by saying that since the beginning of my relationship, my boyfriend and I decided to block our exes from our lives. Whoever, on one occasion, I found her number unblocked in his phone. He explained that, she keeps calling with hidden number so it’s easier for him to have her number saved and just cancel her calls whenever she calls. But I refused to let him have her number and he blocked her.

Fast forward, when I got in touch with his ex, she told me that they have been having affair behind my back. That he impregnated her too and made her go through abortion. She also told that during my getaway with him, she talked to him (meaning he never blocked her number).

I confronted him, and he denied everything. He made her call me back again and deny everything, telling me that my family and his family made her say those stuff and it was never true. When I confronted him about the recent call they had, he admitted and said she persuaded him to talk to her. By saying, the whole town knows about your getaway blah blah, that he never intended to talk to her. Hence he also told me she called from blocked number. Since then, he changed his number.

Few weeks after I came home, I told him that I’m going to talk to his ex. Cause things where sceptical to why she changed her mind after talking to him. He refused, and refused. But offered to talk to her himself and that I could be on the phone and listen to their conversation. In stupidity, I agreed. He got her number by his sister who is friends with him. They met and she again denied everything. I’m feeling like he is making her deny stuff....

Nonetheless, last week, me and him was watching a video on his phone. And guess who called.... yep his ex. He spat on the phone whilst saying “fuck you” and cancelled the call. Now I remember her phone number from the last time she called. I confronted him and he said that it was a cardealer that desperately wants him to buy the car. I told him to call back the number, he refused and admitted that it was his ex. And that he forgot to block her number after that meeting they had. He “forgot”. I said to him, I’m going to call her. He keeps stopping me. Even broke down crying and telling me to trust him. When I ask him why he doesn’t want me to talk to her, he answered that she will only start drama and he just wants her to disappear from his life. Why is he like this do you think? And I feel like he is protecting her, am I right?

Guys please share your thoughts and how would I confront him and what shall I ask him?

Pleae please
