I've been with my girlfriend for nearly two years.we live quite far away from each other but we to see each other as much as we can.recently I found out that her ex boyfriend has been chating to her via Facebook and I know that he's asked her out on a couple of occasions.I do trust her and she says that she loves me and isn't interested in this guy.but why won't she make it clear to him that she not interested?in the back of my mind I have a horrible feeling that she is telling me lies and it's only a matter of time before goes back to this guy.
