I'm so disappointed in my dad's relationship with my children (11&13) and genuinely unsure what I should expect.
He's 75, single and in good health, drives and is fairly well off.
We live locally, I take DC to visit him every other week or we go out for dinner - he often pays for dinner if this is important. In the last 3 years he's visited us twice.
He's never taken DC out without me and never suggests anywhere we could go other than restaurants because he can't cook. He's never taken DC to a park, to get an ice cream on the seafront where he lives or the cinema or any other low effort/low cost activity. He doesn't initiate any interaction with them bar asking how are you and questing DD about school as she is quite academic.
For DSs recent birthday we went out for dinner and he said happy birthday but his only other comment was 'is it an educational game?' when DS told him about buying a Fortnite voucher with his birthday money. I feel this was facetious not curiosity.
DC don't particularly enjoy seeing him, they are polite but i guess it's boring. I feel they get so little from him that soon enough they'll say no thanks to coming along and I can't say I blame them. If he doesn't want to put any effort in to bonding with them, he's going to get very little back. AIBU to tell him this? Or do I just leave it?
