I've NCd for this.
Last week we were away with PILs and BIL's family, and I had somewhat of a lightbulb moment. I've always been somewhat frustrated that my relationship with PILs has been awkward and strained and I've realised it is because they just don't like me. It was particularly stark seeing how they treat their other DiL who was there. They would do things like complement her outfit, praise her for her parenting, generally show an interest in her whereas they barely speak to me, in spite of me making an effort with them.
When we got back both other DIL and I posted photos of the holiday on SM and MIL commented on here but not mine. I sent them an email with an article I'd written thinking it would interest them and they have not replied or acknowledged it.
They barely speak to me. They don't make small talk and never ask me for example, how my work is going which I think is because they don't approve of me working as DIL and MIL sah. They didn't approve of me reading books on holiday and it seems to surprise them that I do, even though I am a writer and read voraciously and they have known this about me for 22 years.
And I just can't figure out why they are like this with me. We don't have loads in common but I have always made such an effort with them over the years, I've always organised lovely gifts, invited them round, provided them with 2 lovely grandchildren, been loyal and devoted to dh and yet they are like this. I'm not sure what I can really do about it??
