my dumb self choice

Taylor
He was accusing me of having something to hide cause I put a password on my phone nd wouldn't give it to him. Reason for that was to show him how I felt when ever I'd ask for his phone me he'd become so angry, thinking I was looking for something. For the record, I was. Two months ago I had randomly opened a message from an unable contact on his phone and found it was a girl replying to a message from him asking for her Snapchat. After that, I discovered countless amounts of unloyal activity, from nudes to giving his number, to making secret media accounts. You name it he did it. Never found out his true intentions, instead I took his word on never physically cheating and that he'd never do it again. Why? I'm truly in love with him. Best friend for years and I just couldn't see a life without him. I still can't. Since then, I found minor things that mad me upset, nothing too bad but still upsetting. I learned that every time he became suspicious of me being on my phone or looking at him funny would always indicate he was up to something bad, bad meaning something he knew I'd never approve of. Well sure enough, after not touching his phone preventing asking or looking at it, I finally picked it up. New email account showing his new snapchat, new dating membership, new lol account, and lord knows what else. Not exactly sure how I should react. For some reason I still want him. I've showed pain, sorrow, insecurity, understanding, &I still find no sort of respect, honesty, nor commitment to changing his unloyal ways. This is honestly more of a rant than anything. He thinks I'm able to talk about this stuff to friends and family but I don't. At least not about everything. I hate hearing how I just need to leave and move on. I've even tried doing all that and it doesn't help me. I'm completely stuck and have no idea what to do. I'm a very vengeful person and if anyone else were to do me wrong, I would want to get revenge some how. But I don't like the thought
 of him being hurt, especially by me. This man has put me through the ringer financially, emotionally, physically, mentally, and socially. He completely took over my life and I still want him. Shows how stupid I am.
