I am unsure of what i am to him.?

ok so i've been seeing this guy i met at work. We've been going out, talking on the phone and have slept together (we started in november of last year, but stopped doing it in april of this year) i found that a little odd. but its ok. We met a little over a year ago. He was recently promoted and was transferred to his own store in june i told him i was gonna miss him, but he asked what i was talking about,that we were still gonna hang out and we do, we still go out and talk every night on the phone, we text good morning every morning. Its kinda cute. i obviously have feelings for him, but i don't know what he feels for me. we have one friend in common and we do the double date with them all the time. one time we went to a couples thing on valentines day, but he has never asked to be his girlfriend. He has always introduced me as lupe (my name) never like this is my girlfriend lupe. we have never had a fight. We've spent all the holidays together. Although i haven't met his family and he's only met my mom. i wanna ask him what i am to him, but i don't wanna seem needy, or pushy or to look desperate. I might be a little of all that. lol but i want to know if i should do anything. or just keep it how it is. He is a really nice responsible guy. He is 26 I am 23.
