Her dad is probably not going to "give her the house." Where does she think he is going to go? And how us she going to just "get a car." It sounds like you are more sensible than she is.

It would be an achievement, if you could find a job. That's a good goal. But you would need to be in that job for at least a year before you would have any business taking on the responsibilities of a wife and child. I think your instinct that her plan is not a sound idea is a good one. Listen to your gut.

Would her father possibly be interested in you moving in to his house with him still there? That might be an option to explore, depending on how long and how strong your relatuonship with this young woman has been.
