My Dsis is terrible at relationships. I'm worried about my nephews as they get dragged into another potential mess. In the last few years she's:
-had multiple affairs whilst married to DNs dad
-left her DH and moved new man into the family home 4 months later (they'd been having an affair)
-moved all their DC into new home together 12 months later
-4 months later discovered he was cheating, new home in his name, he threw her out
-came to live with me for 4 months
-moved into housing association
-8 months later has moved in with her new partner of 6 months.
I can't keep up with her. I worry constantly about my nephews.
My question really is would you say something? Get involved? Leave her to fuck up again? I just don't know what to do anymore.
