I'm just now going through that. I was just rejected by a good female friend of mine when I told her how I felt about her. She just told me she'd call me tomorrow. I know that she won't.
We were supposed to go to a concert soon, but then this happened, so I sent her a message saying she ought to just find somebody else to take her.
Saying that made me feel like shit and want to apologize so I sent another message saying that if she wanted to still go with me I could take her, but the message didn't go through, she already blocked me from her phone. That hurts hard.
So I say fuck it. I've been through it before. The difference is that before I didn't let go. I still pursued the girl that rejected me for three years, ignoring other girls. Now I know better, that if she's rude enough to just straight up block the calls of a friend who loves her then she's not worth remembering.
She sure was fun, though.
