First I think it’s really important for you to learn to be alone. To me this is the key to the entire process. You tolerated a lot of bad behavior for a long time partly because I think you were afraid to be alone.
I always laugh when newly divorced guys say they want to just date and have fun. Scotty B most middle age women don’t want to just date and have fun. Now I am not saying it’s not possible but most women are not want going to want to be there to amuse you. Nothing wrong with going to parties and hooking up with single women. It’s just not as simple as I want to date and have fun.
