Sorry another IL's thread and in advance for long post.
DH's Mum and Dad's divorce came through end of last year after a very messy breakup, which DH and I supported MIL through. DH opted to stay in contact with his father, even though he had an affair. DH is a very kind gentle person who wants everyone to be happy. He is angry with his father but still wants a relationship with him, especially as we have our 6 week old DD.
The problem is that FIL is a very high earner so MIL has had a huge payout and gets a lot of money each month. SIL has always been spoiled and never wants for anything, all her clothes, makeup etc is top brands and she has never had a job. She refuses to speak to her dad now but still gets £500 a month from him. As SIL is seen to be on her mum's side, she gets shopping trips etc. We on the other hand have worked our arses off to get where we are - renting a nice, slightly expensive house in a nice area close to both our families, working full time, several promotions each - with no handouts whatsoever and MIL has not once praised DH for it or even acknowledged it.
SIL still lives at home, jobless. MIL has bought a lovely family home style house with the divorce payout, for SIL. I don't want MiL to buy us a house but the discrepancy with the way she treats her children really annoys me. She does all this for SIL, but when DD was born she said she would buy a travel cot for us. When we visited her at Christmas she hadnt bought it as it was too expensive (the one I chose was £40) so we had to go and get the Moses basket.
Whenever we see them the matter of the house is brought up, SiL complaining of having to get up early at 8am to go and choose wallpaper for "her" house, and it just makes my DH and I annoyed. We have mentioned it to MiL and she just says "well if you want a house ask your father".
In addition they irritate me about DD, such as repeatedly saying that SIL is DD's only 'real' auntie as I only have a half sister and a stepsister, so they should not be called auntie, MIL shouted at DH to be nice to his sister and let her hold DD when we refused as it was her bedtime, etc.
At this rate we will end up going NC. Any advice?
