Dangerous relationship with my mother in law

WARNING ***LONG***

So a year ago exactly my husband and I hit a rough patch. Lots of fighting, caught him trying to fuck the girl he worked with... he decided he didn’t want to be with me anymore so he got his family involved. His mom would set me up situationally and make me angry all while secretly recording me to use it as evidence of me being “unstable” when they took me to court. His mom convinced him to try to take my kids from me... he cleaned out our savings account to get a lawyer.. his brother told him that I that I was unfit to be a mom because he heard the secret recordings of me being upset...

horrible. Just a living fucking nightmare. Long story short my husband decides it’s all mistake and chooses to stay with me. We go to therapy, he quits his old job, he gets diagnosed with bipolar, adhd, ptsd, depression and gets puts on meds. Therapist told us to cut his family out for a while and we do. He improves. We move to AZ for a few months and found that we couldn’t survive there financially... so we fucking have to move back. 💔 we own our home and rented it out before we left the state, but stupidly (BIGGEST MISTAKE OF MY LIFE) we left out a clause in the lease agreement stating that we can evict the tenant with proper notice. So the renter is there until July 2020, and guess where we are stuck.... WITH MIL!!!!! 💔🥺😞😞💔💔💔 we are trying to get approved for a second house loan but the mean time is a fucking nightmare.

Fast forward... mother in law knows that I am still suffering from what happened a year ago. They all go to kids birthday parties and leave my kids out while they are in the house. They all talk about our situation to other family and blame me for leaving the state. She tries to say I don’t pay enough attention to my kids and says I’m really not welcome there but because my husband won’t be without me she lets me stay. and it’s just a flat out nightmare.

I tried to be a big person and bought Christmas gifts for his entire side and found out a couple days later that they all got together (all the cousins, aunts, uncles, etc) for a Christmas party and intentionally lied to us to avoid my kids from going. (Her excuse was, well I know how Chris (husbands brother) doesn’t like you so I wanted to avoid conflict. At first she was saying oh.. I forgot there was a party. It slipped my mind, but the truth eventually came out). So I get upset and she just tells my husband “I feel bad for you being with her bla bla bla”.

I am just kind of terrified of her trying to set me up again with secret recordings since I am in her house. There has been lots of poking and prodding and I’m scared she’s waiting to try to take me kids from me. I know she doesn’t have legal rights but that family is so manipulative and scandalous that I’m genuinely afraid. I am still suffering daily from what happened a year ago but I still constantly get blamed for everything despite my obvious efforts to move forward.

Can anyone offer any advice on how to make these last few months on living with her bearable? What should I do... we literally have no where else to go other than a shelter and o don’t want my kids to have to experience that.

Any advice would help. I’m hurting and I’m scared and I really need help to get through this.
