You left a possibility open. However, he slammed that door shut over and over. I was in the same situation a few years ago. No close friends, only my mother and kids to spend time with, an emotionally abusive ex and way too much time alone. I joined a walking club. It was me (age 42 at the time) and 5 senior citizens walking in the local shopping mall on Saturday mornings. 5 of the kindest, most caring people I ever met. Those 5 people changed my whole life for the better.
I'm a stranger, but trust me, go out and join a club, take a class, talk to your neighbors, walk with old ladies. Try new things and find activities you enjoy. There will be others that enjoy the same things and you will meet them. And your life will be a lot less lonely.
