Oh jesy that's what I mean about being too vulnerable to remain friends.
I shall tell you something that I did a couple of years ago. It's great for improving your confidence and also for focusing on yourself. I think I've already mentioned this on a previous dating (or other) thread, so apologies if you've read it before. But it might help...
Write All About Me on the top of a sheet of paper.
Then make lists of all the things that make you you. But focus on the positives - it's not supposed to be a laundry list of the things you don't like, it's supposed to celebrate why you're brilliant!
I couldn't include anything about looks on mine at the time, but I think I could now...
But it should include things like personality; hobbies; interests; talents; values; etc.
They have to be expressed as "I am..." or "I can..." type statements statements, because those are the most powerful.
So I included the instruments I play, the fact I go camping and my academic achievements amongst all the other things. Just all the stuff that makes me me.
I also put on there, things that I aspired to be. So "I run" (I didn't, but I wanted to and started the C25K shortly after so it became true. I also said "I am healthy" (I wasn't particularly at that time, but I lost 2 stone shortly afterwards and have kept it off).
But basically it became a 'profile' of me, who I am and what makes me me.
I know it doesn't always sound like it from my posts on here, but I'm much happier and more confident now than I've ever been before in my life. And a lot of it is because I became 'active' in my own life rather that 'passive' in it. It helps you change the things you don't like and focuses your attention on the stuff about yourself that's great.
