Don't think that I haven't considered that very distinct possibility, so cool it with the "too blind to see it comments". Are you familiar with principles? I am a very principled person (as best I can anyway). I don't disrespect others and then demand respect. I don't show bias and then demand equality from others. What anyone else does or doesn't do has nothing to do with what I myself ultimately do. That is all on me. Therefore, I will not cheat (premeditatedly). If she does, then that is on her and I'll drop her like a hefty bag, but for me to do something that despicable just to get what I want is hard for me to swallow. There again I am not saying that in a moment of weakness if all circumstances were right, the stars lined up, whatever, that I wouldn't have sex with another woman (she'd have to be really special though).
So, my rock is that I am married, but won't cheat. My hard place is the fact that even if I left I still can't sleep with anyone else. This only makes sense to a principled and morally conscious person.
