You both need to separate if either one of you can't be friends or even more than friends
I just found out that my boyfriend cheated on me with my best friend. We got him back and caught him in the lie. I am happy about it. Shouldn't I be sad or mad tho?
Again not lying
You should be happy! Be happy that you found out sooner than later. Now you can move forward and on to someone who will appreciate you.
