Answer Yes you should end it. If you didn't love him enough to be loyal to him what's the sense of pretending that you really love this guy.
yes. Why...?
You should have known that he didn't love you when you found out that he cheated on you.
No.
if your girlfriend cheated,you should end the relationship
yes , but if i love him i will change his mind
how do you know if your boyfriend has cheated
Sounds like you need a better boyfriend.
Next Boyfriend....
No, of course not
tell her that her boyfriend cheated on her. she needs to know.
obviously that person is going to deny having a fling with your boyfriend
First off, tell your boyfriend. Second, you need to think about if you still want to be with your boyfriend and get things straightened out between you two.
