I met my ex on another site and we discussed deleting both of our profiles. I deleted mine right after we moved in together and he told me to delete his, but I told him that HE needed to be the one to push the button -- not me. Needless to say, he never deleted the profile while we were together, but did so THE DAY he moved out. That kinda confuses me. Anyway, I now have profiles on 3 sites which is more than the 1 site I was on when he and I met. So do what is best for your unique situation.
