nightmare inlaws

I moved in with my inlaws because me and my partner couldn't live at my house because me and my mum don't get along, but that's a whole different story,

So when I moved in the agreement was I paid £40 board every 2 weeks 

20 was for her to save for me 

20 was for household builds 

But then we We all agreed as a household  that my board should be saved for me and dan (my partner) save for another home or IVF treatment 

So I was giving her £80 pound a month for the last 13 months and I should have saved just over £1000 

When I asked for the money ( the money had suddenly disappeared) so I was gutted and shocked but later found out his mum was giving the money I give her to her daughter for whatever she wanted!!!!!!! (Take aways, baby milk, her bills!!!)

She didn't think I would ask for it!!! 

So now I'm waiting for my money and not paying board 

This isn't the only thing she is very nasty at times 

She comments on my home life saying "I actually care about my children unlike your mum" she calls me a liar and lodger out of the blue, if she is arguing with her son she will say "she made you say that" or "are you happy now" when I could be in the shower or in the most random place and she's such a jealous person.

At Christmas I was showing my mum my tree and because their was presents under the trees I got called a trouble maker😫

I buy my own food in but my mother in law eats it! 

I buy food so that I'm not eating their food and yes I do buy myself a treat like chocolate or crisps however their mine, she will eat my food before her own then complain if I do have some of her food, like I buy white bread and she always eats brown however she feeds my bread to the dog when she sees fit, she eats my food without asking then when asked she will argues and get angry saying "your causing trouble you are" 

Perfect example of this is I bought a galaxy bar of chocolate it was eaten the same day by her it was a massive one!! Her excuse? It was on the side, she reads my letters when I leave them open inside my draw she and her daughter slag me off my partners sister doesn't get her kids to call me Aunty and when I try and encourage it she says no into my face, 

she is always called me "big" 

When she is in the house I try and avoid her because she's the type to just randomly start a argument for no reason, so does anyone think I'm being extremely unreasonable? 

Dans sister is also very rude me we made a hour journey to her house to see her kids because she kept complaining about dan not seeing the kids, she turned us away at the door?!? 

Is this disgusting or is that just me? My family would never do this to me regardless of what they was doing?!? 

At Christmas (she knows we are trying to save) she wanted us to spend £50 on a present for one of her kids when we didn't get her it she went in a huge mood 

We spend £80 on 2 children for her at Christmas and she was still not okay with that all I got off her was a mug 😩

There is so much they do, I have to lock my door when she comes over to the house (Dans sister)

Because she looks though my things 😩

 Daniel does stick up for me but it's hard 

We want a baby, we are trying but my partner has a low sperm count so that's why I said IVF treatment (non of our family know) but if we did have a child I wouldn't want them to call Dans sister aunty or had Dans mum around a lot tbh, so does anyone think I'm being unreasonable? 🙈
