Thanks rechu and MickeyCheeky.

Legally- I won't pursue anything. A) because I just got done with a 2 year legal battle lol no more lawsuits! and b) because this is technically my mom's house. At the end of the day. And her right to keep. We never had anything in writing because I didn't want any documentation that my ex could use that could infer I 'owned' property, even indirectly. Somehow he still found out I was living on my mom's property and brought it up during the settlement but because we had a lease in place, I could argue it was just an investment property for my mom. To be honest, maybe that's why she started thinking of it that way?

I think more than anything, I'm just not sure if I should push the issue or just keep making my rent payments and treat her like a landlord. Because that is how she is treating me- as a tenant. Not her daughter. But a tenant. She has been throwing money in to this house I wouldn't have and at this point, if she wants me to pay what she's invested- its way more than I originally budgeted. So, let's say she does want to sell it - do I pay the extra $15k she has put in to it? Even though she made that decision outside my budget proposal?

My boyfriend of course is VERY irritated by all of this and worried because of the stress its causing me. It doesn't even feel like 'home' anymore. We've talked about me just saving up and buying another house. But, this'll be my dream home #2 I'm leaving. I had to sell my first dream home when I first left my ex and I have rebuilt my life in 2 years only to be back in this situation. Argh! Not fun. But, that's life I guess. I am hoping that maybe she'll ease up. Maybe she'll sell the house to me. Maybe not. I am just going to take it day-by-day. I just sometimes feel stuck in the middle. Between my mom, these companies she is hiring, her using the garage to store her things, and then my boyfriend who doesn't like it and is irritated and wants me to stand up to her. But if I do, she's just stubborn enough that she could say "Get out when your lease is up" and then I'll really be in a pickle.
