I can totally relate too! (39 and never had a relationship)

It's tough to date these days for either sex (although I think women still get approached more often than men).

I LONG for someone to look at me like I am the only one that matters but most people, especially women, seem to look 'through me'.

The saying that gets me the most mad (and is somewhat paradoxical) is:

"You have to be okay with yourself before you can be okay with somebody else."

Well, the problem with this is that it feeds on itself.

Lack high social functioning skills, therefore,
you find it hard to feel accepted, therefore,
you withdraw more, which,
hurts your esteem more and makes you feel worse about yourself.

The theory is to break the cycle by "fake it till you make it". I, however, have been unable to successfully do it.

Probably doesn't help much but it's the best I got.
