Should I or should I not block this person on Facebook?

So here is the situation:

I have a facebook friend who I occasionally talk to that is male. He is the type of person that can say the wrong thing and be mean when “joking”. He has never really done anything personally towards me until today. Today I posted a status about the Xbox One. He proceeded to post a pokemon meme picture that said “Suddenly…....a wild opinionated bitch appeared”. Then he commented and said “Love you but I had to do it lol * runs away *”

My boyfriend saw this post at the same time as I did. I was very upset but he was absolutely livid. Like extremely so. I had to prevent him from saying anything because I felt like that would make everything bad. I proceeded to delete the status and messaged him that he had really crossed the line. He said that he was joking and he’ll delete it (he didn’t know I had gotten rid of it already).

My boyfriend wants (demanded) me to block him (and I did for now). However, I feel like that’s unnecessary. Unfriend possibly but blocking to me is REALLY extreme and I have only blocked one other person on my Facebook. I feel like he knows what the line is now (he has never tested it previously) and he won’t do it again. But I feel like if I unblock him I’ll make my boyfriend extremely upset. This facebook friend however always posts interesting topics and whatnot, not to mention I’m slightly afraid of being roasted by him for blocking him (he has done this to people).

I feel slightly like my boyfriend is being controlling and mean in this situation, but at the same time I understand his feelings. I care more about my relationship than a facebook person, which is why I blocked the guy to appease him. But what do you all think?? Is my boyfriend being too controlling? Should I leave the person blocked??
