There's this guy that I really like, and we've been flirting with each other until we started dating. We dated for a couple of months but then he just became really distant lately. He doesn't text me as much and just pretty much ignores me. I go to the same school as him, but I'm not in his classes. One of my friends are friends with him. One time when I went to my friend's house, he had texted her when he was supposedly ignoring me! What should I do?
