It "might have?" Don't you know for sure what happened? Didn't you guys talk about it?
Quote: at the time she broke up with me but I tried desperately to get her back
Had the two of you broken up before she slept with this other guy? Or was she cheating on you before you broke up? Your post is not clear on that. At first is sounds like the cheating happened after you broke up, then later you seem to indicate you were still together when it happened. If you had broken up, it is none of your business what she did while you two were apart, nor should you be obsessing over it. If you were together when it happened, she apologized, you accepted it and if you were serious about forgiving her, then you need to let it go.
Quote:constantly find myself looking at his Facebook just getting angry not having any closure
Stop torturing yourself by looking at his FB page. What good does that do? As for closure, that is seriously overrated. You have chosen to stay with her even though she cheated. She has chosen to be with you. There is your closure.
