Oops, I added much more if a rant since that post haha sorry!
They just seem to all lie to each other all the time, but my SIL has said "They're family so what can you do? Just forgive and forget" but to me being family should be even more reason why you don't do that sort of thing to each other.
I'm done to be fair. I'm not going out of my way to help or even when they offer help and I accept they still seem to be disappointing so I told hub y I am taking no favors either :-/
Just went and re-read. As larrabee pointed out, at least your husband is on your side about this so it will make it even easier! Honestly, you aren't mean. It can be tough enough moving countries, regardless of the amount of time that has passed, that you don't really need to deal with extra negativity as far as in-laws come. I would say it's not mean at all to do what you can - for the sake of it being your husband's family - but not go out of your way to do or take any favours beyond those you decide you want (and if that means none, it means none). Obviously I don't know the whole story with your in-laws, just what you've mentioned here, but it seems they aren't really making things any easier or stress free for you. Sometimes you just need a good rant, so definitely get it all out of our system!

If you stop caring, as hard as it might be, you will definitely have less stress and it actually might improve the relationship you have with them because in a "best case scenario".
