here's a little unsolicited advice. be yourself all the time. most of the time when I see peoples marriages fail, they would go into this 'dating behavior' mode whenever chicks they where interested in would come around. you can only keep this up for so many years. eventually they figure out who you are and if they don't like what they find they leave, taking half you stuff with them when they do.
embrace your iner-pig, be yourself. it's a great filter. you eliminate a whole lot of omen you would have never got along with anyway, before you spend your money/time on them.
