I'm 0 for 3 with marriage - the scoreboard doesn't lie never has. So what we all have is a marriage of the heart. To sully or contaminate or radically disrespect this union with a shameful contract is something that I will leave to the amateurs and the Bible grippers.
I hope to one day co-sign a lease with another person but well it doesn't plague me that I have yet to do so. Put it this way: I've never had to violently tug at my own pillow at 2 A.M. to get myself to stop snoring.
