How to deal with in-laws who don’t like you

I came on here to vent!

My husband and I have been together for 11 years and I have never felt welcomed into their family. We have a few kids together and I feel constantly judged. Over the years his mom has judged my parenting and has made many passive aggressive comments to me. I’m usually a pretty laid back person and have stayed quiet over the years but have been dreading our encounters each year that goes on. I try to be the “bigger” person, but not sure how much longer I can take.

She argues with me about my kids vaccinations. When I told her I wanted more kids, she said no, you can’t have more kids, kids are expensive. ect. She makes those sly comments, laughs and says it jokingly but its rather annoying and hurtful.

I read a book about boundaries and had a long discussion with my husband about setting boundaries with his parents because none were set and I haven’t really spoken up about all the comments she makes.

We had a conversation with his parents about an issue we had while they watched the kids for us, safety issue, and his parents both blew up. They said I’m ungrateful (I thank them up and down) and his mom called me a psycho.

I feel helpless. I tried to take action and now our relationship is worse than before. Anyone else deal with this?
