Having a lot of drama with in laws 😤

I need advice,

I’m usually good about being the bigger better person and shrugging things off or “letting it go” but after 10 years of doing that.... I’ve had enough. It doesn’t help that my husband always sides with his family or tells me to be the better person. I don’t want to be better anymore, I want to be the bitch now .... 😩😤 it is now effecting my marriage and should I be worried that I don’t give a shit what happens from here on out? I feel like I’m done fighting for myself. I want someone to fight for ME for once ....

The drama itself is irrelevant... if it’s not one thing it’s another. World war 3 in my head, so much going on up there my brain hurts
