DO YOU TELL HIS GIRLFRIEND HE CHEATED?

[mad dawg]

I am very torn about what to do- I started hooking up with one of my guy friends, Scott. It was getting serious in the sense of looking like it was going to turn into a relationship ( 10 months) and out of nowhere I found out ( via this girl "Christina's instagram) that Scott had been dating Christina for about a year. I literally had no idea he had a girlfriend. I immediately stopped getting with him/and communicating with him...but part of me thinks that Christina should know, sine most of their relationship, he had been cheating on her... they are 26 and 27 so this isn't some middle school relationship that is just going to disappear...

I don't want to be vindictive and start even more drama, but I have been cheated on, and would have wanted to know that my man was cheating, so I think she deserves to know?

Thoughts?
