^^^ sorry. I just hate when people spout info like they know what they're talking about. Back to you.
That said, even if her agreement is you live here if you take care of the dogs. Then wouldn't that be an agreement and then she would have to give her notice. I'm sure she did walk the dogs on occassion or have fed them. Kinda like if you're a tenant and you don't pay your rent, he just can't kick you out the next day. The landlord has to go through an eviction process...
But anyways, back to BD -- I still can't get over the fact you looked through her purse. And I wouldn't bring that up at all, because I was thinking about it... if I was a girl and had a purse and I found out you looked through it, I'm sure I'd assume you looked through all my other belongings and well... shit's gonna go down if that happened to me -- if I'm coked out or not.
