Threesome is never a cure

I have had several threesome hookup experiences with my ex-wife. One year before our divorce, we wanted to try new things. We thought that threesome dating might be able to save our marriage. At that time, we barely talked to each other. there was no passion between us. We were trying to bring everything back to where it should be by changing our lifestyle to swinger lifestyle. But it didn't work well. We ended up cheating on each other.
