I am a senior in high school and we are on winter break right now. I have been texting this girl from my school over the break. We would sometimes text for hours. First off, i would always have to start a text conversation. Is that a problem? Also, new years eve I tried to text her and she never texted back. I tried the next day and no response. I haven't tried to text her since because I didn't want to seem like I didn't have a life and I was clingy. when should I text her again? One more thing. In early December there was this party where you were supposed to bring a date but you didn't have to. She told me she would probably go and ask some random guy to come in with her because it was a discounted price for couples. Two days before the party she asks me in the hall way if I was going and I said I probably wouldnt and that I would I go over to a friends house. Did she want me to ask her to the party or am I just thinking that cause I like her?
Any help would be appreciated and sorry for the long post but I had to put some background info for a good answer.

i think you are wasting your time with her and should ask her out or move on ASAP. You should not spend this much time building comfort and rapport with a woman until you have some attraction from her to you. You are going to be friendzoned repeatedly with this mode of operation

dude these are AFC mistakes.when she makes an offer u act like u dont wana go or put a "maybe" into the conversation. what u did here was to say u were deffo going hanging with ur mate which makes u inacessable to her for futher advances and stops u from changing ur mind. and also ur doing too much texting, go and set up a meet up already. the longer u keep text conversations going the more u get put into the friend zone. it may already be too late for u so dont be surprised if she declines ur offers ( not to say u shouldnt try them)
