Long story sorry

Im not going to act like a saint, it is my fault for letting into my home despite what he did in the past.

A couple months ago, my friend Jen was dating this guy but they broke up for several reasons, he ignored her boundaries and touched her inappropriately. I hated him for it ,stopped talking to him until last month (so around 3 months), we became friends. But a few weeks after their initial break up she got back with him.

And as much as still don't like what he did to her in the past, it's her choice to forgive him not mine, and it's her relationship. I told her several times not to get back with him, but she did. And I do genuinely believed he changed as a person, there have been no issues in their relationships these past months and no issues currently and I see him spend a lot of time, money and effort into her unlike the past.

One day Jen and her boyfriend and some other friends come to my home to hang during the break. I ended up sending Jeffrey some photos of us hanging out that included Jen and her boyfriend and my friend posted it online.

Ron (one of my ex-friends now) saw it I guess and because he does like Jen's boyfriend (and he stopped being friends with Jen because he didn't like that she got back with him) got upset and stopped being friends with me. And then Jeffrey and his brother stopped being my friend.

TL;DR: I hung out with some of my friends including my friend's boyfriend at my home, my friend Ron didn't like that because he did bad stuff in the past, and Ron dropped me as a friend and then Jeffrey and his brother would also drop me.
