[Age of Ignorance]

I would like to echo everyone's thoughts on the matter. You cannot own his actions. You shouldn't feel guilty because you did nothing wrong.

Here's another perspective: I've been on his end. He probably doesn't feel guilty. Neither should you.

Let's be clear, infidelity is a pesky business that everyone should steer clear of. I don't encourage it, nor do I condone it, but the most regrettable part, for him, is the possibility that all will be revealed to his girlfriend, and he may no longer have that steady comfort zone to return to - not the fact that it occurred in the first place. He is a serial cheater, much like I am, and he would not feel guilty about it.

So, why should you feel guilty about it?
