“Whatever financial arrangements you work out, make sure it’s fair,” Mike said. “If someone pays more, they expect more.”

Will the sex still be hot?
The freshness of hot sex with a woman can do strange things to a man. He’s like a deer in the middle of mating season. The deer are so drunk with sex, they have no clue what’s going on — that’s why they’re always jumping in front of cars. It’s the same thing with your man. Under the spell of your body, he’ll do anything you want, including moving in with you.

Enjoy the ride in these situations, both literally and figuratively speaking, but be aware that things could go to hell if the sex goes bad.

Know the car before taking it for a test drive.
Many a woman says she moves in with her guy as a “tryout,” so she can be 100% positive she could marry him. That’s all well and good, but outside of the fact that you don’t know whether or not he uses balding shampoo, you should have a good idea of your man’s pluses and minuses before moving him into your life full time. At the very least, you should know without a doubt that he isn’t an ax murderer, serial rapist or voodoo doll collector.

Unhappy endings.
If you and your man think of shacking up as a “tryout” for marriage, be well aware that sometimes people don’t make the cut.

When Mike, 32, moved in with his girlfriend of one year, she made it clear that it was a prelude to marriage. While Mike was completely open to marriage, he also saw living together as a “test drive.” But as the months passed he realized he didn’t like the car. His girlfriend, on the other hand, thought she had already bought the car and was devastated when he broke things off.
