That's a tough one Carmasia You can control who sees what and who can even search for you if need be.. you have the ability to be virtually invisible and can block certain people from seeing anything about you including mutual friends etc. It is not 100 % but it would certainly help.

I guess you have to ask yourself if there are other methods of staying in touch with these people that you want to without allowing those memories to flood in? Maybe it doesn't have to be facebook.. maybe it could be something else..

I can imagine how hard it is.. and my heart goes out to you..
