I was hanging out with my ex and the girl he's dating. He says they're not girlfriend and boyfriend but according to one of my friends they're always together. She seems nice I actually like her but I'm very lonesome and I kind of want to get back together with him before I lose him completely. At the same time I also have a crush on someone and I don't know if he's very interested in me or seeing other people. My crush says he likes me but I can't tell whether he's actually into me. I'm not really sure what to do, some advice or perspective might be helpful.
