<human>: Provide a brief overview of the text.

I've always been quite nervous talking to girls (M(16)), but I saw this girl (F(16)) around college who I liked and decided that it was time for me to get my act together; I ended up getting her number and we text each other for about a few weeks. 

We met up once or twice and it wasn't awkward and it went quite well, but she suddenly stopped texting me and whenever I text or messaged her she would never reply. This has been going on for about 3 or 4 weeks. My best mate also texts this girl a bit and today we were talking and he told me that she said to him that she doesn't reply to him sometimes as she doesn't want to talk to me.

I feel that I've messed up yet again and it annoys me that I don't know what I've done. It makes me feel quite down about myself. Lately I've been feeling like I'm not and never will be good enough for people.

Any advice?
<bot>: Started talking to this girl at college, was going well but she suddenly stopped replying to texts and messages and I have no idea why? It's making me feel unsure about myself and I don't know what to do.
