She is your girl friend and girls have friends.You must not limit her. You must have confidence in your self.If he is better lover than you and if he can entice your girl. do hell with such cheap, slutty girl. If a girl is not clear in her mind that whom she likes and can change her stance every second day, leave her.
Love is trust and trust comes from confidence in your self!
If my girl can find some one better than me and also fall for him, let her do that!
I was never a back up option!
More you trust your girl , more trust worthy she becomes. If she is loose character, she will cheat even if you suspect.Who needs such a slut ? I don’t, do you ?
Allow her to do what she wants.
