Arguments with my Bf

I try to talk to him tell him how I feel and then he says why are you soo sensitive why are you so hurt over something little that's petty. I literally started crying and seen him smile I was like why are you smiling do you think this is a joke and he got angry and still trying to put me down. I said I'm not getting angry over something little I want to talk I want your attention and you keep on going on your phone , I want you to care when I'm upset at something wether it's something simple or complicated . Then he said that's just your opinion but it's not reality. In reality a lot of people wouldn't give a shit on what you're upset about. And he just keeps and keeps saying all the wrong things I'm telling him that really hurt me I don't like that and he s like I'm gonna show you that I really don't care then he just walked out the room ... IM soo tired of this. I'm probably pregnant right now too ....
