You know Jilly.....my husband's family made me feel the same way. Actually I got into with a sil that I work with. I work with 3 out of 5 sils, plus my husband. They use to step on me a lot, but in the last few years it has gotten better. More of a control issue, especially with the oldest one. She causes 95% of the problems in the family business, but of course she doesn't see it. Anyways, when my sil got into with me she said my husband was always getting pulled in the middle. Jilly, I swear.....I have never, ever made my husband feel he had to choose. But I am his wife too, on the other hand....ya know what I am saying here? It nearly broke up our marriage a few times. This is why I think that for the most part, family should not live in the same town.
Things are better cause my husband did start to see things, her nearly lost me. After 20 some years, I was tired of his family controlling me. I hope your husband can see things for what they are too. Like I said, it has gotten better, but not completely, but not as bad as it was. Take care, I hope things get better for you soon. I totally understand.
