Best to love Christ first, if you have found him. Then you find a like mind, a like heart in the Body Of Christ. Make marrying in Christ a priority over romantic or sexual love.
Then learn about dependency behaviors, search for demonic infiltrations that might be causing family disfunctions. Learn about manic depressive types and passive-agressive behaviors, and so forth. Note if every day with this person will be a new battle with new rules.
Look at the parents of the prospective love. Note the family realtionships. Their relationship will show what to expect with your love.
Then you examine the living skills, social skills, parenting skills. Are they able to make a living for themselves. Can they sing, play music, enjoy applying a fertile mind. Can they discover life and laugh at themselves. Can they love and cry and allow themselves to be vunerable.
Then after you are finished with your education with a living skill in hand, prepare to dedicate yourself to this person, and serve Christ until you reach the next life.
Remember your spouse is someone with whom you will serve Christ, someone with whom you will raise normal rational Christian children, children who will know Christ's love because of the parent's example.
