Set aside all of the other stuff, kids/house/careers/wills. Do you want to marry HIM? Him in the morning with morning breath, him in the bathroom stinking it up, looking at him mowing the lawn (quiet down you dirty girls, I'm talking the green grass outside), him napping on the couch on Sunday afternoon with a football on TV. Him next to you in bed each night, him at the dinner table each night, him putting a sweet baby to bed each night, him cooking you dinner or coming in the door after a long day at work. Him telling you he loves you every day. Do you feel good thinking about all of those things or does the thought of it make you want to run the other way?
Look at ALL of it, all the flaws and all of the GREAT things about HIM - not the "man of your dreams" that doesn't really exist b/c that man is only in a fairy tale - Look at this man for all he is. If you still have to talk yourself into marrying him after REALLY looking at it all, he's probably not the one.
