How can you tell whether you’ve got a friendship on which you can base a marriage?
When you see the problems in each other, do you just want to run away, or do you find a desire to work on them together? If the second impulse is yours, you have the makings of a marriage. Do you obsess over your partner’s external shortcomings or can you see the beauty within and do you want to see it increasingly released? Then move forward.
