I understand the anger over the affair. But to compare it to relationships she had before you two were together suggests there is more. I think you have a handle on it. If you were more confident, old relationships, I think, wouldn't bother you as much.

Think of it this way, she strayed, and now she's interested in coming back to you. There must be something there she finds pretty damn attractive to have to swallow her pride and want to return. And that's after she thought she would find something better elsewhere. She screwed up but you can be confident that she see you as worth having a relationship with.

And presumably the work you've been doing on yourself had already convinced you of that, independent of what she thinks.
