Ever stop Dating years after the Divorce?

My Ex left me 10 years ago. It wasn't a bad divorce, and we ended as well as we could.

I started dating pretty quickly thereafter. I regret that because I was rebounding. All those little relationships became more serious, and then I would ditch them.

I let some time pass, and got into a couple of serious relationships, but I eventually felt trapped in those as well. So I let some more time go by and eventually ditch those relationships.

Now I have not dated in two years, and in the last year many FB friends and coworkers keep hinting and flirting with me. I never take them seriously. But they keep on me, checking on me, and trying to get me to engage.

I get panicky even thinking about another long-term relationship. I avoid even getting myself set up to even get near one of those. So I avoid pretty well.

Unfortunately, I am not the pump and dump type. I do not like one night stands, and now hitting 50, even thinking about that kind of intimacy scares me because I am not horny like I use to be from teens to my 40's.
