<human>: After my GF of 2 years and I split up 3 months ago, it might sound strange but I instantly became a more motivated and in a lot of ways better person. I stopped neglecting my hobbies and my friends. I've started going out more and meeting lots of interesting and inspiring people. I've re-taken up rocking climbing, something that was a passion for me before the relationship and have got back into great shape and met even more fantastic people. I've started back at Uni and am far more motivated to do well than I was in the relationship. And also I have found a job and am enjoying working and saving to go traveling in the summer.

My Ex has moved on and now has a new boyfriend, who seems very nice. I do miss her sometimes but I think I see clearly that I am a more productive and most of the time a happier person than I was when we were together.

But...

I feel like I'm not going to find somebody new. I've never been great with girls, I've had three, two year relationships since I was 15/16 and slept with one other person. I don't feel like I have it in me to have casual sex and short relationships though I would love too. I'm not shy around girls or anything, I am a very outgoing a lively person and have a great deal of friends and some really fantastic close friends, I just don't seem to attract girls who want to be more than friends and this makes me feel lonely and unwanted.

I kind of just feel like I want somebody to hold spend time with like I did my Ex, but while still keeping this motivated person that I have become. It's hard because I am so happy most of the time, doing things that I love, like climbing, making music, designing for uni and writing. However sometimes, when my friends have gone home, and the climbing gym and studio are shut, I just want to cry because I feel like I am all alone.

I guess this just turned into more of an off my chest but I would love any advice that people can give.
