Do you ever get past the contempt for those involved?

Lately I have been struggling to come to terms with the situation surrounding mine and a friends breakup. Essentially, we introduced our girlfriends to each other, then they started hanging out a lot alongside two male friends instead of with us, then abruptly broke up with both of us. We found out shortly after they had been sort of romantically hopping between each other, sexting, lying, manipulating, and obviously cheating.

For me, it’s been tough to get past my contempt for the ones that betrayed me, not my ex partner, but the other woman and men who then took the situation and manipulated it to isolate me. I am going away to inpatient care at a nicer facility to try and help resolve a lot of the issues that have come from this, namely panic attacks, spouts of anger, etc, but I don’t know if I can ever be okay with them or let go of what they did to me because they continue to do those things to other people and show no remorse.

So my question is, do you ever get past it all? Do the cheaters ever seem to get karma or does it just never get back to them?
