Can a relationship truly survive being cheated on?

[Gaijin]

To answer your question, Yes it can survive and succeed.
However, you are still young and I bet with you that you will never marry this Girl. Forgiving is natural and everyone should do it, though things can be hard to forget.

This is really up to you, if you want to live with constant thoughts if she might be cheating on you, which may(will) lead to jealousy, which then leads to breaking up. So if you have forgotten this, and obviously you didn't, it will be hard for you two to really enjoy each other.

Some people see cheating as a "death" sin, while others have a "open-minded" view on it...
My opinion is simple, if you love, or at least date someone, you shouldn't cheat on them, either brake-up and do what ever you wish, or simply don't cheat....

You say it's online, I say she'll do it again....
Your relationship is simply too young, which means you both are obviously not sure if it's the right thing, she more than you as it looks like.

My advice, break-up with her, cause she seems either to be looking for the right guy, or, she's a b****, sorry....

Taking her back is fine, if you two were already over 3 years together, otherwise it's all justplaying around and testing thins out....
