Fb to me is a double edged sword. On one hand it is awesome to keep I touch with people you can't always see and little things like pictures of friends and their kids etc.
on the other hand W gave me a large hatred of fb. Not because A started in it but it was a tool. And she posted meme's and things that angered and hurt me. I fixed that by deleting her.

So here is my take. If you want to go onto FB because YOU want to do it! It's your life. Don't live in fear of what H thinks or says. Also I'm sure there would be lots of friends here that would be happy to connect with you.
However if it is something you are doing because of H or to get a reaction from him then that isn't the right reason. I learned that here, doing things to get a reaction aren't about you and DB.

Just want to say you ladies always give me a smile when I pop over to visit.

The person that you will spend the most time with in your life is yourself, so make yourself as interesting as possible.
