Should I be the one to text first?

Idk if I should apologize or text my bf if he’s ok. Yesterday, I went with my personal trainer to work out. It’s a girl. He knows that.

So were texting and he asked me what I was doing. I told him I was waiting in the car for my trainer. We were going to work on legs. My bf got so upset.

He told me I better not post videos or pics. He told me he doesn’t want me bringing up the gym “bullshit” again. He told me “don’t text me for shit you ruined my mood”

I was angry and told him “ok that’s fine next time don’t tell me about your hobbies or your fiends either. Next time don’t be posting on social media either”

It’s been day 2 of being ignored. Don’t know if I came off too aggressive. I hate being ignored. .
