My boyfriend is jealous of my past exes?

midnight223
My boyfriend is extremely jealous of my past ex's. He goes on my Facebook profile all the time and asks who each guy is, and who they are to me. Sometimes asks to screen share to see who I've been talking to. He recently saw a comment(an old comment, I didn't know my current boyfriend at the time) on a profile picture of another ex saying I looked nice and now he wants to me delete it. What should I do?
