Should I stay or should I go?

I have always been a black sheep, from the time I was young I grew up in a large, close family with an aunt who hated me so she rallied the cousins to do so also, I wore gl as a child so I was stereotyped a "nerd" and so on.....now im married & have a family & my husbands family & i got along very well for years but a couple of years ago he mother ( who is very opinionated & outspoken) decided to "tell me off" in a very mean & personal way attacking every inch of my being and I was devastated, but I have tried to reach out recently with that good ol olive branch. His sister whom I usually think of highly of but know she gossips and knows my boundries is my husband "best friend" and everytime he & I hash out a big one he calls her in turn she calls there mother (among others Im sure). So now they have decided to rally up against me let my husband know he too good for me although our issues are equally ours I feel so hurt & angry. Both my in laws have issues of there own that I choose not to be hostile about and I could. This situation is making me think about leaving my husband I feel like he should keep our business to our selfs, I dont tell my family and they treat him well. I think deep down inside he actually like the pity he get from is family. I refuse to be a black sheep any longer I want to be in a happy and loving family
