Bf/ not bf issue?

Ive been seeing this guy for 2 months now, he calles me his girl in front of his friends and family but says were not dating, but we go to movies every once in a while. Ik he has really bad trust issues because his ex would cheat then blame him for cheating when he didnt so i guess i understand that part, but what do i do if he doesnt consider me his gf but calls me his girl? Im so confused and ive already asked him a few times but i dont think he understands why it upsets me.
