I live about a 2 hour drive from my DF and SM (DM died when I was 11, DF remarried after I left home so SM not a "mother figure" kind of SM iykwim). They are very lazy and not keen about coming to visit us. Mainly I think because SM calls the shots with DF and can't be bothered coming to see DF's family when if we go there it is usually incorporated into a get together with her DC and DGC.
It drives my DH mad to the extent that increasingly I have visited with the DC while DH was (genuinely) busy doing something else. This has happened on the last two occasions I saw them but I had invited them to us next month for a joint father's day/my 40th birthday lunch and they had accepted. Just now a phonecall saying my DF is having a minor op that week and can't drive that far (far enough) so can we go to them and make it a get together with SM's DC/DGC, etc. Which would be fine if it wasn't for the above history of one sidedness. We can't possibly not go but DH is going to be so peeved...
Others with family who won't visit (other than proper medical/age/financial reasons), do you suck it up, say live is too short and do the visiting or do you only do what you feel is a fair effort?
