First of all, sorry if my english is not that good. Not my first language :P but tried my best.

Hey everyone, basically I met this girl at a party and she added me on facebook, some days later she arranged plans with her friends and she told a friend of mine to invite me but he lied and said I wasn't going to come. She randomly texted me saying that she wanted to see me but I didn't want to (in a funny way of course) so I told her I could come but then she said that the plans were cancelled because I wasn't coming, so I asked her out of course and she said sure, some days later she changed plans and wanted to see me at a party. I arrived and she was there but she didn't look good (not physically) so I said what's wrong and she was just ignoring me.. After that I just decided to have fun with my friends and some hours later she texted me that she was sorry, some things happened etc. etc. I said I was going to do a little reunion at my house and she agreed to go, but she arrived at about 2 am, everyone was gone by that time. We just spoke in her car for about 5 hours, deep things, I was going to go for the move but she really didn't seem in the mood so I went for some rapport, kino, all those things. I found out that she was into her ex boyfriend so bad and she couldn't get over him, so I knew that is bad news, but the more I knew her, the more I liked her. ( I wasn't really into her that much so I didn't care if nothing happened) Days pass, I decided to talk to her a week later (she was subtweeting me things and teasing me with jokes like calling me little baby and things) but from here, everything goes downhill.. I started being more insecure the more I talked to her, I just don't know why, and I knew she was getting bored the more we saw each other due to me being a little insecure boy. So I decided to invite her to dinner (yeah good idea.......) she did something unexpected, she changed plans and wanted to come to my house and "watch some movies", instant win for me there. But please, don't kill me people, I don't know what is wrong with me, when she came to my house I just don't know why, I started feeling insecure out of nowhere and never made a move, she even started to bite me in the back, don't kill me people.. She left at about 6 am.. Me, realizing I screwed up so bad, I decided to text her saying that I liked the way she is and shit like that but she didn't even applied the "seen". I know friends, I screwed up in the most horrible way possible hahahaha, but she still mentioned me on twitter from time to time, same things, calling me baby and teasing me, I texted her in a playful way about the tweets, she responded playfully too, but now I sent her another text a few days ago, she doesn't respond, no tweets, no snaps, nothing.

I should just leave it and learn from this nasty mistake I know, but I'm still going to see her, she is going to the same parties I go, so.. Next time I see her, do I just go full on her or leave it?

Yes, horrible to read, I know.. Any tips on how to regain that confidence? it's not really AA, it's more of a "the more we talk, the more insecure I get" thing...

Thank you for reading :)
