I’m so hurt

This guy I’ve been seeing just stabbed a knife through my heart and self esteem...

In front of me he looked up “blow job tips” and doesn’t see how that is offensive and rude.

This is coming from the same guy who hasn’t even eaten me out.

I told him how rude that was and he said he doesn’t see how that’s rude and that we all need room for improvement. I wanted to die in that moment y’all.

I’m currently in the same bed with him while he’s asleep fighting back tears.

I’m very insecure of how to please him because he’s slept with about 50 girls and I’ve only had 3 partners and I never feel like I satisfy him leaving me feel very low about myself.

What do I do?
