But not her future alone, you see your future with her.
You see not only the two of you in her future you see her walking down an aisle towards you on her father's arm.
You see her glowing while 9 months pregnant. Glowing like only a pregnant mother can. You see the two of you growing old together.
You see your wedding anniversaries. You see the 25th, 50th, 75th years.
When you can look into her eyes and see all this and more. That is how you know you went from being in love to loving her with all your heart. all your strength, all your mind and all your soul.
