I'll give a little info here, This girl and I went to the same high school but currently go to different colleges. We hung out over Christmas break, and texted back and forth almost constantly until our semesters started. For a couple of weeks, it was a slow back & forth, until we stopped. After a couple of weeks without hearing from her, I sent her a text asking her how she was doing, and that I miss her. Was that a good idea, or did I blow any chance with her?
Believe me, I meant it 100%. I really do miss her.
There isn't anything wrong with being honest how you feel. I've told guy friends I miss them. You can miss anyone. Doesn't mean its creepy. As long as she gets back to you on a positive note I think you are ok.
Yes, it's definitely alright to tell her that you miss her. Girls need to hear that. Maybe she's busy with school, maybe she's started dating someone. You won't know until she tells you. Wait for her response and see what she says.
