I hope to your god you lived together before you decided to do this. My girlfriend has a friend who met a girl, dated her 6 months, then married her to have sex. They never lived together, and since then (it's been over a year, anyway) she's cheated on him, he has said to her face he doesn't love her and wants a divorce, and long story short it's the worst marriage I've ever seen personally. So if you haven't had sex yet (and you're mormon, so I doubt it), if you're marrying to have sex, and/or you haven't lived together, I will say it in as annoying a manner I can:
CONGRATULATIONS,
AND GOOD LUCK.
(cuz you're gonna need it)
(not trying to rain on your parade. i seriously mean congratulations, and I hope, as with anyone, that it works out for the best)
