We were both going through the end phases of bad marriages and it started innocently. We started having lunch every Friday and just venting to each other. I was 33 at the time and she was 31. She had a 6 year old son at the time and I had no kids.Her husband was cheating, after a few other times she had only suspected he was, she'd suspected and confirmed and my wife was just a bitch on wheels with bipolar disorder. Then we started talking on the phone every day and night. She began "popping in" to my office (I'm an insurance agent) and I began to find excuses to be "near her neighborhood so I thought I'd stop by". We started having lunch almost every day during the week and the hugs goodbye were becoming more affectionate and lasting.
She had called me one night and told me she had filed her papers for divorce and her husband had moved out. She seemed upset on the phone and I offered to come over. She said she'd be ok and we could have breakfast together instead of lunch. I told her no problem, I would pick her up, and I'd just come in late to my office and let my secretary know so.
When I got over her house she was dressed nicely and her son had just gotten on the school bus. We went inside and sat at the kitchen table, holding hands as she filled me in on her husband's tirade the day before, and then I asked where she'd like to go eat.
She looked at me and leaned closer and said "We don't really have to go out this morning" and leaned in and kissed me on my mouth.
Within a few seconds we were making out pretty heatedly and the next thing I knew we were naked in her bed going at it.
We did it and just laid in the bed quietly for a while before either of us spoke. It was surreal.
Then we just stared in each other's eyes for a few minutes and were at it again.
I told her afterwards that I had to go into my office but, truthfully, I just really wanted to process what we both just did.
I knew there was no way this could continue long term.
She texted me "Don't feel guilty I wanted this too."
We continued having lunch together every day and continued our affair for several months. I began to suspect that my secretary and the other agents knew we were fooling around.I had filed for divorce about two weeks after we'd started our physical affair.
I finally had to tell her that there was no way that we could have a life together like that. Our parents and siblings would never accept it and her son would never be able to process it. She was upset about it for a few weeks, our lunches stopped, and then slowly she seemed to accept it.
I'm in my second marriage now and it's going pretty well but I still have feelings, physically and emotionally, for my sister. I know she still has feelings for me because my wife told me that she'd said she will never get married again until she meets someone as good as her brother.
When I asked her what she meant by that in a text she answered "You know exactly what I mean. I love you." and I'm pretty sure that I had better not be alone with her ever again.
I regret it because I do love her and now I feel like I have hurt someone that I honestly love very much.
