Yes, to "share feelings" means to have the same feelings or thoughts about something, to feel the same way. If you share feelings with your crush, it means that you both like each other. This expression doesn't always have to be used in the romantic way. Ex: He doesn't share my feelings about work. He hates his job. Ex: I really like you. I was wondering if you shared my feelings?
