Well guys here we go, i hope i could get some advices here:
I was in a relationship for 3 years, i was a very needy and AFC guy, very jealous guy, SERIOUSLY i was out of control, i fired my ex because she went to dance with some friends, after a month or so she started a new relationship and i BEGGED her to come back, etc for about 2 weeks, after that i found the PUA shit and my life changed, all that shit was 8 months ago.
A couple of months ago i picked up a girl who study with my ex and she told me that my ex tells everyone that i beg her, etc damn it that wasn't happening but i'll explain later why it's important.
Well some weeks ago i saw a HB9, in my country is very hard to find girls like that, so i opened her telling that an ex is stalking me and telling her that i was looking for advice, we changed facebook, i added her and we started to talk, in the meantime she broke up with his boyfriend and we started to talk more heavy so i told her "hey i'm going to a party with my guys, why dont you come?" she told me that my ex is one of her friends and that they have a common friend (a gay guy, who HATES ME, seriously) that is her best friend of years, she told me "no ofense, but i have to ask her first" then i answered "no offenses but i wasn't trying to hit you ", well she explained that other ex of my ex is trying to hit her etc etc well we finished the talk. Later in the night my ex called me begging me, telling me about this new girl and telling me that she still loves me so i got FURIOUS because she talks shit about me across the university so we fought heavy and i asked her to don't call me again.
Some days later i had a date with the HB9 i like, it was great we have a lot of things in common and she is pretty hot etc etc 3 days later i called her and asked her to date (first mistake i forgot everything about phone game) she told me she couldn't do it because she was going out from town but she invited me to go with her, i told her that i had plans (i invited her to a party) so i couldn't do it, 2 days later i called her again and asked her to go out (again phone game...) she told yes but the day we were suppossed to date i was in business troubles so i couldn't do it so i called her and i made a plan to make a plan, i mean, i told her "i'll call you on X to see you in X night", before i finish the call she told me that she was going to a reunion with my ex and the guy who hates me (what a cassuality) and.... that's the last time i knew something about her! The day i had to call her SHE TURNED OFF THE PHONE (well it was yesterday LOL) and today i saw her in facebook and no talks ... guys i'm afraid that some of the follow things could happen:
-My ex told her how needy i was.
-My ex asked her to don't date me again.
-I looked needy because every freaking time i called her was about date, zero phone game.

I know that the second option isn't that bad, friendship between women isn't that solid like between guys so i don't worry about that.
But the other two choices really worry me, guys i really want to hit this girl she is hot and nothing in my town is like her, what do you think i could do? Thanks in advance
EDIT: I and the HB9 are 23, my ex is 19
