Well, my family seem to really love being friends with all my exes. They have days out together, let them borrow their car, go to my siblings home and have even babysitted exes new child overnight on one occasion etc. I find this odd considering one cheated on me and just generally treated me badly - my family know this. I am not asking them to be mean but definitely cut off from that level of interaction, if they bump into them just be civil and no more.
My family are pretty strange. When I was a teenager my parents moved my siblings drug detoxing ex boyfriend into the family home.
What’s annoying/hurtful is I get accused of being controlling when I bring it up and have been told that they can be friends with whom ever they wish.
