Wow I'm impressed, you actually went and asked her. 7 pages ago you had a different tone!
Was it the right thing to do? I don't know but I can tell you that most of the time you ask online this is the kind of advice you will get, and these kind of rejections seem to happen a lot, all the time actually. Maybe you can try with the other girl who was hanging out with her!
I mean it happened to me that I was inviting one person, and got declined (she had something to do) so I just turned around and asked another one who was around, and she said yes.
Also it's so much easier when your "emotional investment" (obsessing) is not so high, it makes it easy to spend time with her be and makes it more enjoyable for both.
I'm not saying thats good or bad, that's just how it is.
tzuka wrotedon't give up on your first try.
That might work too. Never had too much success with this approach but I can see it working. Be careful thought don't burn yourself up trying to get through a wall. Be wise.
Too bad it didn't work out, thanks for updating us.
