I cheated on my girlfriend ... does that mean I don't love her? should I tell her and end things?
Why would you cheat on her if you loved her?
I don't think I would have done it if I loved her.
Cheating on your partner is wrong. You should tell her the truth but she will probably break up with you over it.
If we break up I wont have anyone to party with.
It is wrong to cheat on her. IF you only think about partying it might be better to be single if you don't want to commit.
