You should have looked for answer five years ago, Then you may have found the problem and fixed it. There was a reason you married him. But it started going bad and you did nothing to fix it. Now it is probably way too late. You are probably going to end up with "your crush", but that may not last so long either, because you do not understand commitment.

Why don't you try to be faithful again? If it doesn't work out, I'm sorry. However, it doesn't hurt to try. This divorce won't only hurt him. It will hurt you, too. If you don't like this answer, I'm sorry. I'm just speaking from the heart. I just don't want you to do something you'll regret later. If you are truly unhappy, follow your heart.
