My FIL passed away a few months ago and MIL is very lonely. She is spending Christmas with us and it's made me realised that as she will be staying with us a lot more often (she lives a 4 hour train journey away so will stay for long weekends/a week) and there are times we would normal be seeing my family for Sunday lunch etc that she will be with us & I'm not sure how/if it's fair to just expect my family to accommodate her.
Also, my parents own a house in Devon so family get-togethers happen most main holidays and now MIL is on her own, it seems obvious to bring her but I'm just not sure
. None of my siblings or parents would say no and obviously feel bad she's on her own, BUT I suspect given the choice wouldn't have her there. This partly because they don't know her as well, but also she is quite draining as she talks non-stop and becomes very Hyacinth Bucket around my family (very difficult levels of wealth/class if there is such a thing anymore) and it's really awkward for everyone so I (selfishly) wouldn't always want her there.
How to handle it? Accept she's very much part of my immediate family now and apologise/explain in advance and give everyone an 'out' or keep her at arms length as far as my family are concerned even if it means less lunches & holidays for my DC. If it makes any difference, if she doesn't come away with us she won't get a holiday so do always feel bad about the family weeks we spend together with DC other grandparents knowing she'd love to go away with us.
