This is probably the straw that broke the camel's back but I really think the time has come to go NC with my dad.
I found out that he and my step-mum have been visiting my sibling without getting in contact or arranging to also see me. My sibling lives about 40 mins from me and my dad lives about 4 hours from us both.
He has been to visit my house once in the last 4 or so years. When he has come up here the only reason I know about it is because my sibling (who I'm very close to) has told me.
This is on top of many other hurtful things he has done over the years - and I've just had enough. AIBU to think NC is a valid option?
