This is an incredibly sweet idea. "Open when you need to know how much I love you; open when you don't feel beautiful; open when you need a laugh; open when you miss me; open when you're mad at me; open when you need a date night, etc.
These are my greatest flaws. Unfortunately I'm flawed in my love portion of my life. I couldn't be a jerk to my friends, or think I'm better than everyone else. Nope, I had to be a complicated mess. pretty much says all
When things change, people change. There's a point in life where you get tired of chasing everyone and trying to fix things, but its not giving up. You've got to do what's right for you, even if it hurts.
