I Feel Like He Doesn’t Want Me

Overall my bf is a great guy. Works a lot, smart, funny. We’ve been together a year and a half. I’m almost 17 and he’s almost 19. Lately though I feel like he doesn’t want me. We snap each other all day but when I make a conversation w him I find his responses dry and he’s been taking a while to reply as well. I’m scared to talk to him about this because that last time we argued he got mad at me saying I always make problems. My bf has no filter which is what usually creates the problem. He literally says whatever pops into his head and sometimes it hurts my feelings. For example the other night he was taking pics of me and sending it to his guy friend and he put his arm up blocking my vision of what he was typing. He said it was a joke but Ofc I was like what’d u do that I couldn’t see? And he got mad saying I’m picking another fight and that he was joking around etc. It kinda made me upset so I guess my eyes got watery and he kinda made fun/ got mad that I was gonna cry abt it. Then he did another “joke” after this and stuck up the middle finger in my face. Like Ik I sometimes overreact but I don’t do it on purpose. I just don’t know what to do anymore:( I love him so much.
