N.B. English isn't my first language.

So my boyfriend 23Mand I 19F have been together for a little over a year. In the beginning everything was going fine in our sex life; he'd clean me up, ask if I'm ok and if I want anything. About a month or 2 ago I notice changes. First, I'd have to clean myself and he wouldn't give me no aftercare, he stopped asking if I'm ok and things like that. Today, we had sex and I told him my belly hurts and he was like hush. I got up and went to clean myself (because he wouldn't do it) and when I was finish I was so shocked to see him casually scrolling on TikTok and mind you I'm in pain. He then got up went to clean his self then went right back to his phone. Afterall this I was obviously upset because over and over again I told him I hated when he did this, so I asked him to drop me home and he became upset. When I was home I said to him the next woman you get intimate with ensure to check up on her when she says her belly hurts and don't just go on your phone, he ignored me completely. Now both of us is home and he didn't text or call me and neither will I. I just don't know what to think.....
