Rough patch

My boyfriend and i have been getting on each other’s nerves lately. We’d get into little arguments and I’d just start crying. I’ve been crying at least 1-4 each week. Idk how to stop being emotional bc I’ve never been like this before. And when I’d start crying, my boyfriend would push me off if I was laying with him. He told me it’s bc when I cry while laying with him , he thinks it’s his fault. I like to be comforted and hugged when crying, but he doesnt do anything like that, Even if he does, it’s like limpy and feels like he doesnt care and just wants me to stfu. When I’d cry, he’d tell me to stop being a child and act like an adult. Idk what to do. I’m lost because when he does that it makes me cry even harder. I wanna fix this but idk how.
