Advice real quick would be great.
Met girl in class.
Hungout & had a couple of makeout sessions during that hangout.
She sends me texts that same night saying how much fun she had.
Couple days later I text her to hangout again during the day & a she says it's her brother's bday & asking if i could that night and that she'll let me know by 4. I don't hear by 4 so i shoot her a text @ 5:40ish saying "how's tonight looking" (probably a bad idea, but didn't really care) no response.

Had class with her today sat behind her we didn't say a word & she didn't come up and say hi. So I just kept talking to the kids around me.

What are your views on this?

Bump.

Literally a sentence of advice would suffice.

Alot of times we get busy, if you push the envelope to much you may come off as needy, as far as when you saw her at school again, if you pretty much ignored her completely that could be bad. The hard part is figuring the line between to soon and to late. she may be shit testing you

She was dressed up today as well & I attempted to make eye contact before she left. And we usually went to the library together after class and she didn't wait just bailed after she was done with her worksheet & I stayed since I was still working on mine.
I was considering shooting her a text asking for a woman's opinion on some bs today or waiting until Sunday. Thoughts on this?

she honestly sounds like she told you she would let you know if she can't make it and you fell for texting her hey are you coming, right into her trap, dont text so soon, she fucked up she should have to contact you end of story.

She could possibly have buyers remorse because of this, or she seeing someone else to

Agreed, appreciate the time & posts
