She won't TALK to me....HELP!!!!?

[Blink]

I knew this girl for sometime in my boxing team and we were friends on facebook...we chatted a little and during that time I think I overdid it and didn't play it well....then I deleted my account for personal reasons and then I got her phone number and we texted during summer....not serious stuff....I got over excited and texted her a lot....then I dissappeared had to change my phone number for other reasons...and now after 8 months...I got her number again...I sent her a text saying we could go out sometime....she said yes...then I texted her where she likes to hang out and got no reply....the following day she won't speak to me at all...and she won't befriend me on my new facebook....

Should I try to ask her why she's acting like that? I know I've been really strange too but I feel really bad...she seems really interesting and I want to get to know her better....but she completely ignores me when last year she would wink at me...I think I screwed it up....how can I make her see I'm not some weirdo?
