MIL birthday is on Sat, DS birthday on Sun. Hadn't heard anything about any plans so assumed they'd be a fam meal / party for DS on the Sun and Sat we'll take MIL out for lunch. DS is 21 this year. DM and DS are over at ours two weeks ago and ds sees a message on dm's phone about a surprise party for her birthday. We hadn't been told anything about the party but assumed it was just for her friends and we would carry on with the sun plans (nothing spoken but this is what we do most years). DM had sent an email out to DS friends to organise paintballing (clearly i can;t partake!) and food etc at their house before / after but we were not included on that email or told anything about it til ds saw that message. Then dm text later that night to say i;m organising a surprise party hadn;t told you as it was paintballing but you're welcome to come for a bite to eat on sat. I said sorry sat is a no go as dm birthday but we'll celebrate on sun. DS said we could see her on Sun (before / afternoon something dm has booked in London) as did Dad but then DS retracted saying she can;t do sun at all (I suspect on DM's say so). I know what they have booked and it is booked for 7.30pm for 2 hours which leaves all day free for us to see ds.
Dad has now texted dh saying im sure your mum won;t mind if you change her luch til sun as dm (in other words) will go mental otherwise.
DSIL birthday is also the day before my DM so historically we have always bent over backwards changing plans for DSIL to accommodate my DM on that weekend (in another month). And generally speaking, if we are seeing Parents and PILs in the same weekend we always end up making it most convenient for my parents rather than dh's.
I am less than 3 weeks from giving birth. History of tension with "D"M and have gone periods without speaking as she has done some things beyond imagination (cruel and vindictive) for no reason other than that I got married and she struggled to cope (I believe she actually has a mental illness of some form that drives her to behave in this way, she has had depression previously).
Whenever dm gets the hump she just stops calling / texting etc. which has happened over the last few weeks and to be honest i can't be bothered to make the effort. She should check to see how her 18mo grandaughter is doing iff nothing else!
Feeling emotionally blackmailed (again) and v pissed off about the whole thing.
