As a woman, I fantasize having sex with my ex husband. We had the most amazing electrifying sex. We screwed eachother everywhere, all the time. We had a 2.5 year old. I have not seen him in a year because he’s irresponsible. I don’t collect child support, for my peace of mind. I still think of the sex and I live in my parents house with my daughter. Mind over matter, it’s just ridiculous. He sent me flowers last week for my birthday, maybe that triggered it for me. Very difficult season for me since I chose not to become involved with anyone even after our divorce. I hope this is normal and will pass.
