No If he is cheating on you or other women I would suggest you move on or not go out with any men or boys cause they cheat, lie to you as well do some harm into the opp set sex. such as abuse women or girls and assault them. If that doesn't work Good Luck
If you can forgive your sister, you can forgive your boyfriend. It doesn't necessarily mean that you should stay with your boyfriend. Cheating is cheating and if that is not acceptable to you, you should find someone who will respect that wish.
You should tell your friend that he is cheating its best that she knows.
He's cheating on you.
if u think ur bf is cheating on you and then he will have a fit about it.
if the emails are of a sexual nature then i would consider it cheating
You should tell him that you know that he's cheating on you and tell him how you feel about it. Also if he then goes hmmm... ok then just do the same back if your a bitch or if your nice then just dump them.
your boyfriend
The only way you will know if and where your boyfriend is cheating is either ask him straight out (he may lie about it) or, take a girlfriend with you on an evening he should be with you and follow him.
Address him about it face to face.
talk to her tell her how you feel
Yes, and I'm ashamed on you for cheating on your boyfriend with his cat.
You should tell the other girl and both break up with your boyfriend.
