pretty much as it says, DH has been NC with his dad for about 30 years, they tried to reconcile about 3 years ago, but dad wasn't really bothered. DH's siblings have also been NC for a long time due to some false allegations and efforts to wreck our marriage.
it now seems that FIL is getting forgetful and DH's sibligs have been in touch with DH and have assume that we will drop everything and run too FIL's aid!
DH says absolutely not, and i agree but are we being unreasonable? his dad has wanted nothing to do with his son for 30 years, his siblings have wanted nothing to do with him for at least 7 years, so why should he now be responsible?
