My relationship with DF (late 70s) is at a very low ebb following a row about Christmas several years ago, where he told us he'd never spend Christmas with us (me, DH, 3 young DC) because he wanted to be with DSmum and she always wanted to go her DD and DGS. (All live at long distance so no popping anywhere for part of a day). Massive row followed which resolved nothing.
We are not welcome at their house (Dsmum's house into which DF moved), they won't stay at our house, hear endlessly about how wonderful DStepgrandson is, DSmum sees us once a year around Christmas, and yet DF insists our DC call her "Granny X" and write her thank you letters for gifts. They barely remember who she is.
DF is classic passive conflict avoider, though he is clearly trying to be assertive since he married DSmum (i.e. by telling us that he is doing things as she wants!)
We had thought we were meeting up with them pre Christmas at DB and DSILs house. However it now turns out we are missing them by a matter of hours as they have to leave early on Saturday to drive long distance to DSmum's DD and family. So much for my DB and DSILs plans to have a big family lunch.
DF has now made contact to suggest options for meeting up. As it's now a week till Christmas we don't have any dates free before mid January. Either they can come to us, or we can meet half way. They can only come to us if local hotel has availability (since they won't stay with us). They won't invite us to theirs.
I'm tempted to stay stuff it, DH and I have had enough of all the snubs and pretence we are important to you, but this would end relationship. Can't decide whether to do this or maintain moral high ground as usual with a brief but cool meet up so that DF can see his DGC.
Any advice from those with similar difficult dynamics?
