She was not my tenant... This is my house she stayed with me... It's obvious that you can not help me.. you're not reading the messages.. No where in there did it say I was somebody's landlord
What's obvious to me is you don't want advice, you only want support for your (erroneous) reasoning that you should be able to dump the stuff already. Well, if you want top chance her suing you and you having to reimburse her for her stuff, go for it.
Personally, I'd like to protect myself from such a legal problem.
1) She lived there 7 months. Even if she never paid a dime to you, that makes her a resident for that period, and you are legally the landlord.
2) Proper notice is not a text message. It is not 20 text messages. Proper notice that you want her stuff out is an old fashioned snail mail letter (certified is nice, but at least keep a copy) informing her that her precious property will be disposed of if she does not retrieve it by x date. 30 days makes you sound reasonable and professional.
State a deadline, and stick to it. Attach an inventory, so that it is unambiguous what you consider to be her property. It makes it more difficult for her to say later that she "didn't know" you wanted the stuff out, and makes it more difficult for her to claim that her washing machine is gold plated.
3) Be polite and civil. You have been rude here, and none of us have imposed on your hospitality, so I can only posit that you're even ruder to people with whom you have a legitimate gripe. Seriously: legally, being polite will help you come across as credible.
