Need Help??!!

I work in a shopping centre on my days off from college and I met this girl that works in a shop next to me. She’s a cool girl and she’s pretty funny and social like me. As soon as we met we had crazy chemistry and we were back and forth on snapchat for a month straight. We had a lot of inside jokes that we made and always had something to talk about. I would tease her a lot and she called me rude (jokingly) so I knew I was getting somewhere.

Anyways, we had a couple dates at a Hookah place after we finish work and sometimes she would pick me up from my house in her car sometimes. They were all fun and we both had a good time. We talked about our past relationships and she told me how she’s only ever had one BF.

This is when things change: So basically, one day I posted on my story and didn’t want her to see it so I blocked her from seeing my story. Somehow she found out, most likely cos I have some of her colleagues on my friends list. She confronted me asking why I did that, I was surprised how she even found out and denied blocking her at first then I later admitted that I did and told her it was because I didn’t want her to see the ‘negative’ side of me. Anyways, she accepted my apology and things got back to the way they were.

So now a week later I get a call from her phone, so pick up and a guy starts speaking asking who I am and asks why I’m calling this phone. I couldn’t say much as I was at church and couldn’t argue so I just hanged up the phone. Next day she bursts into my store saying that it was her over-protective cousin was the one who called me (as B.S as that sounds) and went through her phone and saw our calls and messages. I was really pissed off and let her know that it wasn’t cool. She said she understands and was sorry that happened.

Anyways, 2 weeks later she unfriended me on all social media even though we didn’t have any other issues. After this happened I have not iniated anymore contact whatsoever even though I’ve got her number (which I’ve deleted now). And it’s been a month since I’ve last spoken to her, even though she works in the same centre (awkward). I spoke to her colleague who’s my friend and told him this, he said he been un-friended also, and she’s been off work for 2 weeks but came back recently.

I don’t know how to play it now, plus it’s killing me inside that I still don’t know why I was un-friended. But I don’t want to go back to her first so I don’t look thirsty/needy. However, she was a really good girl and I rarely fall for girls these days so wasn’t hoping to lose her, but I will cut her off if necessary.
What can I do in this situation because I can’t think logically due to emotions affecting thoughts. Look forward to your help guys!!
