After a lot of back and forth on your part, you decide that you're not ready to be completely exclusive with the guy you've been seeing. Instead, you both decide to keep things how they are and continue to just date each other. Things are going well, until you’re both invited to a mutual friend’s engagement party.
As soon as you get to the party, both of you proceed to drink far too much and before you know it, you’ve lost track of your man. The next time you see him kissing a girl who you recognize as a friend of a friend. You want to scream at both of them, but you also feel like you don't have the right to, so how do you handle this?
