Well if you both lay down the law on what's okay and what's not okay, provided the information you've given... I guess it doesn't sound TOO horrible.

Propose the idea, see what she thinks, just don't pressure her into it. If she says maybe, give her time to think. If she's unsure a week later, sit down and write pros/cons
