Advice for guys...
  1. Don't get married for sex
  2. Give expecting nothing in return.
  3. Show up unexpectedly at her house a few times when she's not there and sneak into her bedroom.
    This will give you an idea of what your house is going to look like if you do marry her.
  4. Observe the way she treats her dad, and consider it very seriously.
    She will treat/mistreat, respect/disrespect you the same way she does him.
  5. Don't marry the girl you can live with; marry the girl you can't live without.
