My Boyfriend is cheating on me through facebook?

[The Grim Muscari]

Long story short, my boyfriend left his facebook page up at my house. Turned on my comp, it was there. He had a message open where he asked a girl on a date. This upset me extremely. I haven't told him. Should I tell him or not? What should I do?

DUMP HIM....WHY HAVE A CHEAT AS A LOVER???

BEFORE you think about breaking up with him, tell him that you saw his Facebook page and that you also saw you asked a girl on a date. Then say (name) what's going on.

Of course! If I left my laptop with my facebook account opened and my girlfriend saw that I was talking to another girl I would expect her to say something to me ( and leave me). I mean you need to respect yourself and not let him play you. No one deserves that.
