in considering boycotting DH's family for the forseeable future?

[Shoulddohousework]

Okay, be gentle, this is my first AIBU!
We had DS' christening at the weekend - important day, was part of Sunday Service so everyone had to be at church for 09.30 and then we had hired the church hall for a party afterwards with a bouncy castle and softplay for the kids, lots of food and drink for the adults - was really looking forward to it! Is a big deal to DH and his family that DS' were christened!

Anyway, after the service MIL and her sister storm out of church, get in the car and beep at everyone to get out of the way! Everyone else walks round to church hall and gathers in their little groups (every family occassion is a bit divided - my mam and dad are not together, DH's family do not tend to mix but usually everyone is polite!)
So by now it is about 11am, DH comes up and asks where his mam is? Explain have not seen her!

Okay, this is getting long so will try to cut it down, basically MIL does not turn up until 12.45 stays 20 mins, does not talk to anyone except her sister inc. me and DS's, gathers up her family and leaves.
Would like to point out that she wanted this christening and to be a part of it so had spent 2 weeks previously trying to include her in the preparation at DH's request!

Anyway at about 3pm, DH goes to MIL to drop some stuff left behind to find them all having a party in the garden!

I then find out that MIL's sister was rude to my mam and told her to Fuck off, sat giving dirty looks at my family,
DH's sister was rude to my cousin because she had to ask her to move to get to the children!

It did spoil the day quite a lot for me, and I ended up for feeling guilty because DH says MIL was upset because I made a comment about the food - which I said "Oh my god, look at all the food!" It was not a nasty comment but as MIL was not there, I know it is her sister and her giant wooden spoon stirring as usual!

Damn, this is long!
Anyway, AIBU to avoid going to MIL's, am currently refusing to go round as I know I will say something that may but probably won't regret but DH says I have to go!

This is a difficult one. Your outlaws behaved appallingly. I don't blame you for wanting to distance yourself. If it helps, my outlaws behaved similarly to me after DS was born, but in a more snidey and underhanded way.

I DID distance myself for a while, which they became aware of, and now things with MIL are better, SIL is still a cow to me but she is a sad old soul and I don't give a shite.

I guess what I am saying is as follows. I turned things around with my MIL after distancing myself. She is been much better towards me since as I think she knew I was upset. Could be the same for you. I also did it for DP's sake. Whilst he was privately supportive of me he couldn't say anything to them. He never gave me grief over my feelings towards them but it did start causing tensions and rows. You dont want that.

Sorry I don't agree with the earlier poster's comment about stopping your kids seeing them, it's unfair involving kids in this way.

But I also think that to exclude them from your own life for anything other than the short term is unsustainable in your circumstances.

Sorry if I rambled
