To cut a long story short, after I broke up with my ex-girlfriend she slept with one of our friends who had also recently come out of a relationship. We have both moved on but I found out earlier this week that neither him nor his ex-girlfriend hadnt just before I kissed her in a club. She told me prior to kissing that he had said he still loves her, and she was quite clearly confused about everything.

Its pretty obvious that our kiss only happened out of spite and revenge but she is a solid HB9 and, more importantly, a really nice girl. Should I try and make something happen here?

(Im not concerned about how i could affect him because he slept with my ex just a week or so after we broke up when i was an absolute wreck over it. However, my concern is that it could confuse and mess her up even more)
