Is it normal to be worried?

hmmm depends dose he seem sorry about doing it? did he tell you? dose he seem like hes cheating?

Hmm well I stayed with him. And he cheated on me. I feel so stupid but oh well .

..always a cheater.

Once a cheater...

It's normal to be worried, but just because he has in the past with other girlfriends, doesn't mean he will with you. Like me fir example, I cheated on my last boyfriend because I was ver unhappy for the longest time with him. But, I am with someone different now, and I could never cheat on him. I love him too much. So that saying you said doesn't always apply. It only applies to people who always cheating their partners.

I agree with the previous comment. In addition to that, I think how he characterizes this situation should be considered. If he feels that cheating was a mistake that he hopes to never repeat, then I think he is worth trusting. If he is however, only unhappy that he was caught that time, then perhaps 2 months might be long enough for him to have done the same deed to you?

Allow you knowledege of him so far, and a knowledge of what you honestly feel you could live with help you decide on how to proceed.

best of luck to you!

The past was the past, not to mention a completely different relationship. I wouldn't let it effect your relationship. Plus he was honest with you about it.
