First love

So My boyfriend and I have been together for a while now meeting on his sophomore year and my freshman year. Us being a year older now nothing had changed. I lost my virginity to this guy and stuff but I still just don’t think I feel as strongly as him. He’s always around me. Following me like a lost puppy. When I’m around any other guys he has to touch me and kiss me. I love him more than I’ve loved anyone but maybe he loves me more. I’ve told him and need space but then get gets sad and guilt trips me. I dunno what to do. Help
