However, she's got to determine why she strayed in the first place and be honest about it to herself. After that, then she can talk about her real feelings with me. She's just not at that point. She and the rest of her family have a hard time opening up about emotions, so it's something she has to learn to stop burying or else she'll never be happy no matter who she's with.
Thanks for the comments. More are appreciated.
She strayed from you because you exhibited behaviors that were unattractive and on top of that she probably is attracted to other men who exhibit more attractive behaviors.
She doesn't need to be honest about something you already know the answer too.
If she was attracted to you in the first place, she probably wouldn't have strayed.
