DH and brother have never really had a relationship with FIL, he walked out when they were young and visited sporadically.
DH is now late 30s and FIL lives close by and has a partner (been together around 6 years). He doesn’t keep in touch or visit his grandkids but they spend 3/4 days a week with his partners grandson. Birthdays, Christmases go by and none of our/BILs kids receive a visit or even just a message wishing them happy birthday.
Both DH and BIL have made efforts in the past to meet up etc but it seems a chore for FIL who then claims never to hear from anyone.
It’s infuriating that he has so much time for partners family but can’t make the effort with his own. DH just wants to keep distance now and doesn’t want to bother keeping in touch.
AIBU to expect FIL to do more to keep in touch with his children regardless of their age?
