Was I wrong for leaving?

I left my fiancee in start august because I found out he was sending dickpics and receiving nudes from a handful og other women. It tore me apart. I packed all my stuff from our shared apartment in only 20 minutes, and was OUT while he did his best to deny everything I had photographic evidence of, so I didnt believe him of course. It took 3 days before he actually admitted, not that it changed anything but I can't stand denial.

Basically every day since he texts me these paragraphs about how much he misses me, how ashamed he is, how much guilt he feels and stuff like that. Telling me i'm all that matters, that he is nothing without me. You know the drill.

At one point I told him it was kinda interesting how it only became shameful when I confronted him and that he obvisously didnt feel that way for all the months he did this.

His answer was that he knew, and it was because he realized how much he lost when I shut the door.

The thing is, I still love him and even though I know I shouldnt, i'm the one feeling bad FOR HIM! Spending time comforting him and so om. It makes my self think i was wrong for leaving. That I should feel bad for not accepting his disrespect.

I pray every night for strenght, for not budging. But it is so damn hard when the love of your life chose other women over you.
