Did I do the right thing?

I’m not even sure why I’m writing this, maybe cause I could use some reassurance or maybe because this is an awesome community in which I know I’ll receive amazing feedback and sincere as well so I’m reaching out to you ladies for help.

I went through my bf of 2 yrs phone and found that he was texting other girls again. He wasn’t aware I did that so last night I thought it would be a good idea to go through his phone in front of him and ask him to show me. He accepted but then quickly changed his mind while I went through with it. He admitted I was going to find shit on there That would upset me. I stormed out of there drunk (he didn’t even try to stop me) and on my way out he mentioned how he wasn’t going to call or ever reach out again! I feel horrible because maybe I should of just been upfront with him from the beginning about me going through his phone. At this point I’m done going back to him because that would just mean I have no respect for myself but I feel like I left things on a bad note maybe he doesn’t even deserve an explanation who know I’m just sad because I love him and I’m hurting!
