How am i supposed to tell if he likes me anymore?

One way to tell if a guy is losing interest is if he is becoming far more distant from you than normal. If he usually called you to say goodmorning...or goodnight...or anything in between then something has changed. Also if he is going to other people (especially women) with his issues and for emotional support then he may be losing interest. BUT...there could also be other reasons...he could be stressed out or depressed. Honestly the best way is to ask him if there is anything on his mind or that he needs to talk about. Direct communication is the best thing to help resolve your paranoia.
