The Lonious Monk
Celestial Souljah
You love who you love due to proximity and values.
But as Umar said, marriage isn't about love. It's about joining your life, family, and resources with someone else's. Marriage is a business. Relationships are a matter of time and money more than fleeting emotions. The trick is being emotionally invested in someone from another group.
I don't agree with that characterization of marriage, and correct me if I'm wrong, but Umar isn't married so he isn't exactly an authority on marriage.
I acknowledge that there a financial aspect to marriage. I also believe marriage can be a business if that's what the parties want, but saying that all marriages break down to that is stupid and sounds like it's coming from someone who has only experienced marriage from the outside.
