Hi There Roxiannabell ~
Whew! It sounds like drama at your place. So sorry to hear. I would say, you seem like a lovely,sincere & Patient new wife. And I agree with others here, working for family is hard enough without the close proximity of being under their roof too. Good Grief! Poor thing!
You two have enough history to step back together as a couple & start making some plans of your own. Be a united front & think of yourselves as a little family.
Setting goals together would be good. It goes without saying that work & home changes are at the top of the list. Boundaries seem to be an issue too. Talk to your husband about how best to set them with his family.
Try to carve out some time together, even just to take a walk. Alone time is important for marriage at any stage.
Don't forget: It's not you or your husband. It's the circumstances. Stick together & come up with a plan. Set some little reachable goals.
It will be alright. You have each other And that's huge.
