FIL is super stingy: he comes to our city once a month for work and stays over at our place but never thinks of inviting us out for dinner or anything
I don't think it's unreasonable for FIL to assume that his family will welcome him to their home once a month without expecting anything in return. But I agree it would be nice if he treated you to a meal or takeaway. This wouldn't bother me.
when FIL comes once a month, he sometimes does not communicate what time and ends up showing up too early sometimes
Then your DH needs to make it clear that he'd like his DF to give an ETA.
MIL forgot I m vegetarian for her birthday so I ended up having a slice of meat giving the rest to husband (didn t want to be rude on the spot)
This was thoughtless of her. I presume you reminded her after the meal?
Next day I had indigestion which caused me a loud and long session in bathroom at their place (we stayed over because it is a 3 hr drive), as if I was not embarassed enough, when I got out, MIL asked in front of 10 brunch guests if there still is any toilet roll left in toilet.
she was rude and I don't blame you for being upset at this.
day after wedding FIL asked me twice when we re having babies
I'd have laughed this off.
once talking economy and politics and giving my opinion, FIL didn t let me finish my sentence and bashed my comment by saying „nonsense“!
Surely this is just part and parcel of a healthy debate?
we are expecting a baby And while my friends and family shower us with gifts, parents in law have done nothing until my hisband felt embarassed and told them if they could also buy some things
I think your DH was rude in this instance.
MIL bought cheap polyester baby Gloves (instead of cotton as we asked)
You are bring a bit precious here.
MIL bought 3 baby clothes all of them saying „i love daddy“ none mentioning anything about mummy
Sigh and ignore.
MIL commented „you look good, you are very full“ during my pregnancy
She was rude.
They never get me anything for my birthdays, while my parents think about my husbad when it s his birthday, even if just a dinner...
You shouldn't compare his parents with your own. Different families have different ways (or not) of marking occasions. That doesn't make them any less loving.
MIL is very gossipy about people I don t know (neighbors etc) and keeps on repeating the same stories every time I see her
I'd find this tiring too.
I ve been made redundant due to pregnancy (in Switzerland there s no protection unfortunately) and my mother was telling my FIL that it s no big deal, worst case I can stay home and care for baby 1-2 years and that she also stayed home for 2 years when she had me, his response was that both partners must work and contribute 50/50 financially because it is unfair to put all financial pressure on one person (notice the guy was a big shot himself at a bank and his wife was taken care of most of her life!)
Ignore their outdated views.
I m a mixed child, one of my parents comes from a third world country he had to flee in the 70s for political war reasons, my MIL was a Part time German teacher (when she worked). Once out of the blue she started complaining that she was approached by a volunteering organisation asking her to teach german to refugee families (as part of an integration program) once a week for a couple of hours since she s retired, she was saying: I can t believe they permitted themselves to bother me, I m retired I worked all my life and I want to enjoy it now.... I am so annoyed at this organisation (PS she never had to work hard, only did part time teaching)
I don't see how it being a refugee organisation is relevant. And she is entitled to enjoy her retirement if she wishes, without feeling obliged to volunteer.
FIL asked us if we want to go to their place for his birthday and I answered that I have a friend visiting from the UK that weekend and that we planned it long ago (shey got her flight ticket and all), he seemed quite pissed off
It's possible he was pissed off. It's also possible that you misread him.
I understand some of these niggles. But I also think you need to decide whether you want them Tom turn into resentment, or whether to ignore/deal with those that are unreasonable or need addressing.
