Hey guys, bear with me and sorry about the long post.
I been talking to this girl for 4 weeks now. Mostly texts, a couple of calls. She was into me from a few months ago but we only started talking after a month ago when we saw each other at a nightclub two weeks in a row, we met through a friend of mine. She told me she has been into me for a while but couldn't speak to me before because she had a boyfriend.
Anyway we had been texting each other pretty much everyday all day since then (which I know is a mistake and I effed up here). We have been talking pretty seriously to the point we have pretty much agreed we were going to start a relationship sooner or later (by the way her family is really strict and she has to keep it on the low) and we have built up a lot of sexual tension too. She tells me how good looking I am all the time and how she misses me, can't wait to see me etc she's even told me she really likes me and can't wait to love me.
I've tried to meet up with her before but she was sick for a bout a week and a half with the flu and she then had her periods for another week, so she wasn't really keen to meet up then. I know for sure that she definitely wanted to meet up so I know she wasn't blowing me off. Everything has been going sweet, though the last timi I talked to her was on thursday. That day I had called her and she sent me a text immediately after we hung up saying "you're cute". That same day she had also told me that I'm the only guy she's been talking to.
I sent her a text saying hey on friday night and she didn't reply, there was a music festival on the next day which we both went to, so i sent her another text if she wanted to meet up somewhere (which is anohter mistake I made, shouldn't have sent anything). We ended up bumping into each other I tapped her in the shoulder and gave her a hug and said "I missed you" she only said "oh did you" and said I'll be back and walked away. She looked in a hurry and like she was looking for someone, her friend was holding her by the hand sort of dragging her along so that might have been the reason why she was so dry (not sure). Anyway I went somewhere else and ended up bumping into her again, she walked past me and I gently squeezed her ass, and she touched my back though we didn't say anything to each other. I think she turned around to look at me but I didn't pay much attention since she pissed me off when she had walked away from me earlier and I was pretty drunk by that time. It has been 3 days since then and we haven't spoken to each other since. I'm really into this girl but I'm not sure of what I should do or say next. I don't want to lose her so any advice on how I can fix this situation guys? It's really strange that she has stopped talking to me so suddenly.
My idea is to send her a text saying "Heyy I was listening to this new spanish song today and it reminded me of you

(she loves when I speak spanish to her). Anyway just wondering if we can talk tonight I want to call you cause I think we might need to talk about some things. Ps don't be a stranger this time

" But yeah I'm not too sure about sending her that.
