Trust Issues

So my boyfriend and I been together for 7 months and within those months it's been hell.y boyfriend believes in order in fully know a person is know about there past. Every detail in there past relationships. His problem is that my past relationship there has been some guys that I'm still cordial with whether we was together or friends with benefits. Is it wrong for me to be cordial with the guys from my past? Another things is that he has my passwords to both of my social media and when I ask for his he says no. Should I go ahead and just delete my fb and my instagram or just keep it?
