Learn to accept bf for who he is and not who he WAS?

When you open pandora's box ........ Those things happened before you two got together. It has nothing to do with the person he is today. The fact that he shared them with you truthfully should show you that he is being open and above board with you. The problem seems to be with the way you are accepting his past. Refer back to the opening five words of my answer. Good Luck to you both and you may want to appreciate what you have now and be grateful you wasn't in the mix early on.
