Losing even more trust

(Long story/short) So since the beginning of our (going on two year) relationship, my dude has been so open with his phone. Even added me to Find my friends app. (Which at the time I didn't even know what it even was, google it!) but a few months ago he took me off and I got an alert that says so. I asked he said it was waisting his battery on his iphone. I let it go. Fast forward to last night. In two years I only checked his phone once. Till last night! I kid around saying Ima check his phone and he said go ahead nothing To hide. And even got up and used the bathroom and came back. His phone wasn't locked at that very moment and so I grabbed it! He sat down and continued watching tv. I seen porn on his recent internet search. He looked down at me and at his phone and laughed nervously. But let me continue looking! I watch porn myself and mind you he doesn't and refuses to watch it w me. Don't know why, still! I don't get mad at any of this. No big deal. I quickly scroll up and get on his FB which he is always on watching funny videos but he says he doesn't use it for anything else. I don't care. I don't use FB at all anymore. But I then started to look in his massages. I'm fast w my finger lol read and scrolled up and down real fast and boom!! Ran into a message from January 2016 we got together and moved in November 2015! He was messaging back and forth with some girl (and I didn't even catch her name or pic! Cus I got so upset!) they said hey to each other back and forth and then he complimented her and said she always looks nice! And asked if she was back in NYC! She said nothing at after this point. So basically she's not interested in my man lmfao so! How about if she would have been? Would he go for it? Um I believe so! I immediately put his phone down and stared into space upset. He realized something was wrong right away and started asking me what's wrong? I walked away to think and he came running behind me worried. Well he tried to flip it on me! Asking me to delete all my apps and accounts like Instagram etc. I said, "That doesn't work on me! Stop flipping this! You got caught!" He says no I didn't. But before bed last night I asked him to apologize! Yes that easy! For now! And he said he's so sorry and that only happened cus we weren't together that long! Still! lol and that he'd never do it again. And that he just wants to delete his Fb now. And that when he wakes up he'd delete his account. He doesn't know the extremist I can be. During the night he tried holding me and my body just wasn't allowing it and I kept pushing him away. Now today, he tried flipping it on me again! But I got so upset and kept telling him I don't trust him. He started cryiny sayin no no no stop please. I'm livid! He asked me what can be done cus he feels like this messed up everything and that the girl models in Europe! (Like that made me feel any better!) but I'm an attractive woman and myself also have done modeling in the past. He then proceeded to delete each and every female on his FB besides family. I said yes! Delete em all! And that I should have enforced this before I let him move in w me! (My mistake) I also told him how lame his game is and how she didnt even say anything back to him. And laughed in his face. I said next time it's over. Now ladies! I laugh cus I don't want to cry and make myself feel worst. He's showing me today that he knows what a big mistake that was and im choosing to give him another chance. What would you ladies have done? (Sorry this is long!) 😽
