So where to begin.

I'm 24, been single since I was 19. During that time I've been to uni and had lots of fun, travelled around a bit, had sex with lots of girls, and overall quite a lot of fun.

My problems begin when I fancy someone immediately, before I've even spoken to them I can tell if I think they are 'girlfriend material' for me. I then am quite good (normally) at getting a date and meeting them! The dates (from my point of view at least) go really well and often we will kiss. I then have been rejected for a second date on a few occasions and find myself attached to my phone waiting for them to reply and it really gets to me.

It's hard for me to understand how I can go from really independent and single mindset to allowing someone I don't even know to dictate my feelings.

Am I doing something wrong on the first date? I just feel a bit shit at the moment as this has just happened again and I don't know what to do.
