Hello there..

You're insecurity is understandable, having been cheated on and with her past - but she was honest to tell you which is good. But.. it's not fair to bring both of your histories into the here and now although of course I understand why. Try your very best to wipe the slate clean for the both of you - you guys together doesn't have to end the same way. Worrying about it happening and your insecurities will not stop her cheating again - if she is going to do it, she will, so you're kind of putting yourself through a self-inflicted hell here. There is no point thinking the worse if you see her dance with other men, or talking to other men - the first perhaps she could avoid, but the second is pretty much unavoidable so please try not to let jealousy ruin what you have.

If you're struggling with this, perhaps try therapy? If she has issues too, perhaps couples therapy? If you can't see a way out then perhaps it would be better to split up before you get even more emotionally involved. Prob is tho, that the next lady you would meet may never had cheated before, but it's no guarantee that she never will. It can always be a risk, but sometimes someone is worth taking a leap of faith for and letting yourself trust again.

Wish you luck.
