DRAMA , that's all its going to be just saying, NOT going to end well
Look up squatters rights in Texas and you'll have your answer. Hopefully. If not please let us know how you made it work for you two.
A provider has lived in my home for 6 months . She's great when I get home from work,my laundry's done and folded . Dishes done, floors mopped, when needed . Only drama is with some of her regulars, on her cell. She knows one day, my S.O. will be returning from her country. So till then , she has a place to stay.3-4 days she's at home. No visitors are brought to my home,she takes her business elsewhere.
