Quote from TGregg:
I wonder if you have a full appreciation for the potential that exists, so perhaps one simple and true story will help.
A friend of my family got in on the ground floor on a nice opportunity and did pretty well. Not filthy rich, but solidly upper middle class if not lower upper class. His wife passed away, and eventually a girlfriend moved in with him in his house.
After a while their relationship deteriorated and he asked her to leave. She refused. I think he called the cops, but they weren't about to remove her by force.
Turns out that you cannot just toss your live in girlfriend into the street. He had to evict her, follow the same lengthy process of forms and court dates and notices and get a lawyer and all that stuff just to break up with his POS girlfriend. To offer full disclosure, I don't know if she was paying some money as part of the mortgage payment and/or utilities. Further, I did not talk to him about this, everything is second hand. Second hand from his side of the story, I might note.
Doesn't mean that your girlfriend is the same sort of skanky-@$$ white trash as the victim above's was or anything else. Just a story from some anonymous internet poster that perhaps suggests a bit of consideration can be a fine thing.
