It's very inconsistent---she blocked you, then unblocked you... .my ex hasn't blocked me yet, but last week when his friend wanted to meet up with me for tennis, my ex told him not to meet me, and told him to block me... .it's crazy how they want to control, and why would it make a difference to your ex if you block or don't block their family? I don't get it
I blocked her family since she uses them as flying monkeys and since I realized they are enablers. She uses them to pump them of information about me. She also uses them to have them send me messages that makes me feel bad about not being in contact with her. Among other things. No good.
