Wow! I'm glad you posted because I have the same questions going through my head.
Like you said, where is this going? It's been going through my head since I started the affair about 2 years ago. I don't know but I don't think we're horrible people. It sounds like we are though, doesn't it?
Geeze I could have written your post!!! I'm the same way thinking that I want AP to leave his family and start a life with him....but then the realistic side of me thinks, "this would never work in real life" "how could I trust him if he did this to his wife?" and my family would never accept him, I would be embarrassed to be seen in public with him and the age difference, well... I feel like its not noticeable now but down the road it will be. It's like I should just leave him alone and let him live his life with his family while I build my own life.... but my heart is in crumbles because he gets me like no one else. I feel so comfortable talking to him about anything... I can't picture him out of my life.
So I wish that I could have made better choices in the beginning. What it boils down to is this: If you're thinking of starting an affair (and this is meant for those who are lurking now), really consider your options. Don't let yourself be in this predicament.
I really wish I focused on my studies back then and ignored AP. I wish I would have told him to leave me alone and therefore I wouldn't be where I am now with these choices.
