I was drinking and felt kinda dissed because I wasn't planning on this and I kinda acted like a jerk. sarcastically asking if she gave her number out to anybody. Well anyway I kept pushing it and asked about her ex
Kinda? No, more like absolutely. If you're exhibiting jerk behavior, there isn't any "maybe, kinda, sorta" about it. It either is or isn't.
I'm wondering if this girl was even interested in me to begin with.
Probably somewhat. But then you stomped her interest out.
You're thinking this may turn around? Highly doubtful it will, because the damage has been done. You're hoping it turns around because you're attracted to her cute face, but notice that she's not sticking in there hoping it turns around.
I asked her if she was gonna be around later this week and she told me she didn't know because she doesn't have her schedule from her manager yet.
Notice how she avoided making plans with you at that stage.
Compare it to earlier, before you did your damage:
"I called her earlier in the week and asked if she was gonna be around on the weekend, she said yeah".
She didn't have to hear first from anyone then.
She was going to be with a couple of her friends and wanted me to come. I was thinking it was going to be just me and her. So anyway I didn't want to go
That was actually smart of you to avoid getting into a situation with unknowns and potential c@ckblockers before having enough time in with her to have her interest in you high enough to override her friend's opinions/interrogation.
Now, maybe there was something about that invite that made you feel dissed as you said (maybe it was 'what? she doesn't want to go out with just me?'), and maybe it was warranted to feel that way, I wouldn't know. But to ACT like a jerk and say the wrong things because of how you felt was the mistake. You see that, don't you?
And leaving multiple VMs and calling at 4AM and calling right back from a friend's phone (she suspects that was you) signals an incredible amount of creep factor and neediness to a woman. There's no need to act like that.
If she's being at all civil to you, it's probably because now she's concerned that you may show up outside her window one night and wishes to keep you placated.
