I am a shy guy, but I feel like I've done a good job of meeting people in my classes. But most of them disappear after the semester ends. Though we've traded contact info, none of them contact me to hang out. I'm always hesitant to make the first move. I assume if I don't hear from them after awhile, they're not interested in hanging out. I don't understand. Am I not friend material? I am quite short for my age, but that shouldn't matter.
It's really aggravating and makes me feel bad about myself.
Any suggestions?
