re: Does your non-married significant other split living expenses 50/50 with you?

50/50 isn't right if he owns the house and is building equity. I would want her to pay some but not all. If my mortgage was $1500 I'd expect say $500 or so, just a very cheap rent amount. Also this depends on how much each person makes. Basically you gotta make it to where them moving out creates an easier situation than renting did.
