I've had a live-in MLCer all along and from my vantage point, people going through this are selfish and manipulative. When they do something nice, we tend to think: I think he/she is waking up!
In reality, what I found? Everytime my h would do something nice it was immediately followed by something bad.
She may be keeping some of these routines with you just to get you to sign those papers. I am sorry to be so callous. But MLC is brutal. It really is. The person you knew is gone. Lonnng gone.
Definitely get a lawyer. I know there are legal circumstances where if you move out, you abandoned the home and you lose it. You just don't know what you don't know until a lawyer looks at it all. By the way, the lawyer can look at it and if it all looks great, you don't have to tell her you saw a lawyer! But if it looks shady, well you have to protect yourself and your interests.
Also, stop worrying about what SHE thinks of you. The questions are: what do you think of you and what do YOU think of who she is today? I mean really, do you want THIS person?!?
