Do I text her again? Do I forget about her and move on...? What do I do guys?!?!

I'd try to make this short but that's just not going to be possible so SORRY IN ADVANCE FOR SUCH A LONG POST! So about 2 months ago me and this girl, who at the time I knew a little but knew her sister abit more, became friends. She's 17 so yes, immature in her ways and in general, and I'm 22 (m). Before we became friends, we had the occasional chit chat whenever we saw each other but nothing big.

She told me one day she liked my hair, I said thankyou and that was that. My mate asked me after work if i wanted to go out drinking and ofcourse came out with the usual "and who knows.. maybe you'll meet a girl", I told him what the girl said (she told me about the voluntary work she had done earlier in the day before talking about my hair) and he straight up says "I think she might like you...". Now I've never had a girlfriend... ever. Havent kissed a girl or anything, so him telling me that caught me off a little.

Apparently its because she said it IN my work whilst with her (F) friend and could've easily walked out the shop and told her friend the same thing, but it didnt work out like that. After becoming friends we spoke ALOT, and I mean ALOT! Whenever she drove past my work when I finished my shift, she'd ask if I wanted a lift home, she would even come down from her house to pick me up, and then we'd sit in the car and talk (did this 3 or 4 times all lasting around 1.5-2 hours long, I didn't time it before anyone asks lol).

Anyways, in the 2nd car chat, she stated she wasn't looking for anything yet with anyone (I knew to not ask her out there and then in that moment because she's pretty much just told me but not in the exact words), and that she wants to live life more as she had just got out of a toxic 3 year relation ship (so probably not the ideal choice of a possible first ever GF for myself). All of that was understandable, and I respected her decision.

Ever since then we'd go and spend the day together whenever possible (baring in mind everyone her age was in school but coming to the end of the year so maybe you could say she was just using me to hang out with because she's got no-one else around?). She even said in a text one night she was glad to have me in her life and that I was awesome. She's also said before she knows we are pretty close and she liked it. Btw, this could make a massive difference.... she's depressed and I suffer from GAD and am slowly becoming depressed myself, and need cognative behavioural therapy.

Anyway, since the first day, we slowly and gradually started to talk everyday near enough. At first it was a couple of texts a day but then after about a week it was everyday and for hours on end, and I'm talking about one of the convo's lasting nearly 12 hours... I started to like her but didn't want to come across too needy etc, so didn't say anything and just wanted to see where things would go, and i honestly felt like somehing good would happen between us!

There then came a time where she had a mad argument with her mum and sister and didn't wanna be in the same house with them at all so she decided to stay at her (m) friends house for the night, which turned into 4 nights, but what she had mentioned in one chat previously, was she would probably share the same bed as her mates (M and/or F) whether it's her own bed or her mate's bed. Now I don't know about anyone else but to me thats not right at all, but thats just my opinion. People do that. Everytime we hung out she'd message me after it saying something like "thanks for today I enjoyed it" for example... (with abit more than I've just typed here) and I'd reply back to say I enjoyed it too and things like that, so you know... just the casual text.

She did say she doesn't like messaging anyone first or more than once because she thinks it annoys people and looks pestering, I told her it wouldn't/doesn't annoy me, because it actually doesn't. I'd message her in the morning saying Good morning asking how she was etc. She started to trust me alot and told me things she hasn't told other people and so have I but now it's all different... I messaged her a few days ago saying "Hope you have a fun day with the voluntary work xx ", (she was really excited for the day) but I never got a reply, and thought she was busy and decided to give her space and see if she replay to say how it went.

2 days go by and nothing, so I asked her how she was and what the poppy voluntary work was like and got a reply saying "Hey, somethings came up, I'm not gonna be able to go tomorrow xx" that was it, no "yeah it was great thanks!" Or anything like that. Nothing. By "Tomorrow" it's that we planned to go to a car show (was planned a month prior to this day).

Ive been told she's lost interest so I should just move on and shouldn't message at all now. To leave it. But I don't know.. she could be waiting for me to message but then again I don't want to come across needy or desperate etc. She doesn't like PDA (public display affection) and also never wanted to take 1 picture with me at all but did with others.. and before it all went downhill I didn't know where I stood but think I do now but could also be wrong and have taken all this the wrong way. Me now not texting at all could've made her think differently of me now, maybe not. I really dont know. Maybe I'm just clutching at straws? What do i do? It' been driving me nuts! Any answer is appreciated thanks!!
