Do you run when you get scared?

I don't even put myself in that position. I would rather not have any involvement. I was married for 25 years. The last 10 years she had several boyfriends. I had no idea. We had quit having sex those ten years but dumbass me stayed true and didn't know until I had the stroke and she kicked me out of the hose and stayed separated for three more years. We were going to get a divorce I begged her to come back I still loved her then I found out she had been lying and cheating on me the last ten years. I was in shock. The last ten years maybe more was a lie. When I found out she was cheating I was through. It has been a mind f..k every since then the last ten years of my life didn't exist. So no I don't put myself anywhere near someone else. I don't trust anyone. I shouldn't have trusted her. We spent our whole adult life together.
