Does this sound controlling/emotionally abusive?

A few days ago, my fwb randomly mentioned that he feels like I ignore him because I don’t answer for a couple hours in between at times, while we were in the middle of sexting 🤨, but then also said sometimes I ignore him days which has never happened before. I thought it was weird because I don’t at all. When I tried to say I didn’t, he accused me of lying. Until last night, I didn’t answer because I’m in training for a promotion at work so they temporarily have me on nights and by the time i saw it, was past the time he said he was going to sleep. So because he had already gone to sleep and with how busy it was with training, I just left my phone off. And then knocked out as soon as I got home because I have to wake up with my two toddlers a few hours after. He texted me at 10 AM and was like “see I told you, you do this all the time”. I tried to explain to him and apologized. He said it was fine but then in the next message directly following said “you’re not really sorry, so don’t say that, that’s what pisses me off”. For the rest of the day, he’s been really short. We talked about possibly hooking up tonight too but then he says he’s been too cranky since the morning so he’d rather just chill at home and play video games. Mind you if I ever say no, he tries to push it or he’ll say it’s fine but then acts grumpy. I’ve felt cornered all day because he wouldn’t say much but I felt like I still had to push conversation fast so he didn’t get mad again
