If I'm in a group of people, and a guy likes me in the group, is there anything I can do to find out?

All my friends have someone to text and talk to, and I guess I'm starting to feel a little jealous. I don't know which person it is, and I'm not going to ask, but I'm feeling lonely, and I wish I could do something about it.<br><br>Please give me some hints or some advice.<br><br>If there's anything that I've missed, please tell me!<br><br>TL;DR: Is there a way I could find out which boy might like me if I'm in a group of people with boys in it, and what are the consequences if I find out who it is?
