The background is we are low contact with MIL and FIL, (visits for special occasions and text updates.) this is due to a plethora of incidents, comments and general shit stirring on their part, DH and I decided it was for the best for the DC to not have to be around the constant negativity and victim mentality.
DS1’s birthday about a month ago, he decided (as well as a small party at the house for a couple of friends) he would like to go for a carvery with the family. (I know it sounds an odd request, but we did something similar for his cousin at the end of last year.)
My DM and SDF came, PIL and both BILs (plus kids and partners) all went well, kids loved it, all left happy.
I get a call from DM - who is aware of the situation with PILs - to tell me she has had a call from them. She was ‘cornered’ at the meal where she was asked for her number as they, “must do something at some point.” Now, DM is quite a non-confrontational, reserved person who is always wanting to please others, she never thought they would call, but it turns out they have and have invited her and DSF for lunch with them. (We all live within half an hour of each other, so distance isn’t an excuse unfortunately.)
I though DM was calling for an excuse to get out of this, it turns out she and DSF think it would look odd and very rude to refuse, so plan to go and leave it at that, with no more contact.
My problem is I don’t want them to. I’ve voiced this to DM, but SDF is having none of it and insisting on not being rude. I know that there must be some ulterior motive to this invitation, especially as we have no idea about it. As far as similarities between them go, they are chalk and cheese, this cannot be because they feel they would make good friends.
AIBU to do something to stop this? (If so, what on earth can I do?) Or should I just let it play out? I love my DH dearly, but his parents are my burden to deal with, I don’t want my family having to as well.
