I've been interested in my best friends' brother for about 4 months and he was showing mutual interest for at least 2. I told him how I felt and I also said that I was jealous when he talked to another girl in particular. He didn't seem to care and kept messing around with me when I really just wanted some kind of commitment so I wouldn't feel like s*** when he was around other girls. He's been seriously hard to judge and when a friend confronted him, his excuse was that he was "involved" with a girl that has malaria.
I'm so insanely frustrated with him that I just want to give up, but at the same time it's really hard for me because I see him everywhere and lots of things remind me of him. I can't talk to him the same anymore and he's probably lost interest in me, but I still think about him and it hurts so much.
