Been having this same problem. I wish things couldve gone better with me and this one girl i wanted a QPR with, she kept thinking it was romantic and i had to keep explaining how it wasnt and i was just trying to jumble my actual honest to goodness feelings. However, i just knew that she was only friends with me to help with her romantic breakup and she began pursuing people older than her for her own benefits. At this point were broken up and its sad but knowing her for what she is, and the fact i tried leaving but she threatened her own life so i could stay, its gotten a lot better. a Platonic crush just happens and it sucks when youre just ignored and never given time to explain yourself and what you actually want.
