Don't do it...
My brother did this with his gf. He's finishing up school, has a promising career ahead of him...meanwhile his gf was established in her career and making good money. She bought a house in her name...my brother moved in with her. My mom warned him about how dangerous that shyt is, given that he had zero leverage. I warned him. Told him he'd have to change his ways and start being more lubby dubby with that chick, because lord knows if shyt goes bad you're on your ass. He didn't listen. Two years later they broke up and she gave him 24 hours to move out and find a new place. He ended up crashing with me before moving in with some friends.
