I [27 F] told my family some private information about my boyfriend [28 M].

First time posting here so I am sorry if I structure anything wrong!

My boyfriend and I have been together for three years. We've each gone through and have been going through a lot recently. In my family we are very open about our lives and talk and support each other though a lot. Recently, I spoke with my mom and a couple of my sisters about some of the things he has been dealing with (briefly - not in detail) that have affected me as well. He told these things to me and never specifically said not to tell anyone; however, I know he is a very private person and has never told his family any private details about me. I am a less private person and don't mind if he tells details about me to his family. However, I know it takes a lot for him to open up to people and he doesn't often. It just kind of hit me how wrong it is what I did. I've been feeling absolutely horrible for disclosing a personal thing he has had going on to them. I know they will never mention it to him or to anyone but that does not matter because they know now and maybe he would not want them to know. I really wish I could go back in time, but I made a mistake and I can't.

My question is: Should I tell my boyfriend that I told them this information? Would telling him only serve to relieve my guilt about the matter? Would telling him be the best thing to do for our relationship and for him?

tldr I told my mom and a couple of sisters a private detail about my boyfriend. Should I tell him what I did?
