Well mate, I was in a similar position myself from ages 20-28 - I had the odd 'fling' here and there, nothing too serious, the odd regret, but no girl that I really liked would like me (or, not in the way I wanted at least). And yes, I would take knock-backs to heart too. The trick is to stay positive, stop thinking about it so much. There's nothing worse than thinking life is going to pass you by and you'll be single throughout. Learn to enjoy your own company, be happy with yourself (mentally, emotionally, etc) and you'll be more happy - as it does sound as though you're a bit down about it all. You're still young for gawd's sake!! During that period, I went to university, got qualified, met some really great friends, did what I wanted, when I wanted, travelled the world for a year....honestly the list goes on...yes, there's times you wish you had someone to love you and to love back, but please, do not worry about it....the right girl will come along, whether you know her or not....yes, you will have to make an effort to find her (she's not going to just knock on your door), but don't despair....just have fun...and believe me, girls like being with a fun guy who is happy (i.e. not all cut up and bitter about being single) - hope this is of some help at least....and yes, it all turned out OK for me too.
