Is she OK? Have I done something to offend her?

Damn, son. This sounds rough. I been through situations like that. Part of the reason why I don't have many friends. All it ever does is cause stress that's not necessary to have. But, honestly, what you should do is leave her alone for a while and keep yourself occupied for mean while and in the mist of you being occupied and you'll forget about her, but, doesn't mean you won't miss her. But, while you're doing own thing, in the mist of it, she'll wonder and start bugging you again.. That's what I did once before. It worked. Now, me and that person are friends again, in fact, we went out, but we broke up and stayed as friends instead.
