Not sure if this goes here but its being posted here. So there is a girl that goes to my school and i thought she was pretty cute to i added her on fb. I decided to comment on a pic of hers "Very beautiful in this pic" and she replied and i replied and she asked "have we ever met?" and i replied "nope." Right after that she msgs me and say "hey, what grade are you in?" so we started talking and it seemed like she was flirting with me so i went with it. She was like "im cold right not" and at the time a snuggie commercial was on so i said "pit a snuggire on" to try and make her laugh. She was like "oh i have one but never wear it" so i was like "yea not to many people can pull them off but you would prob be gorgeous in anything" so she replied "thats for me to know and you to find out" so i was like "oh how do i find out" she was like "idk" so i was like "oh you can txt me a pic" said that to get her number so she said oh i dont have your number so i got it. So now we`ve been txting and for the first two days she would like text alot but every once in a while never reply and an hour or so later ide get a msg "hey" so i figured she must want to talk. So now today i txted her good morning and crap and we talked and again no resonse randomly. so like 6 hours late ri txt again "hey" about an hour later no response. So my plan is just dont text her tomorrow and she if she ever texts me but i want some more opinions. Remember we have only txted because we are on winter break and only have txted about 3 daysohh and what if my phone isnt sending/recieving the msgs? i would feel desperate to send each msg twice for assurance
