(I don’t think anyone is using male pronouns, Ron.)
People rarely change. Never expect that to happen, unless you know the person really well, and they are dedicated and disciplined. THis was not a great friendship, so grieve it but try and get back out there. In a few years hopefully you won’t even think of this. In my experience, it’s very difficult to be friends with exes, usually someone has stronger feelings or hurt feelings. Just move on cleanly and you won’t experience so much negativity.
