"My life (my life) would suck (would suck) without you." Hmm. I think she's got something there.
In our early years, the formative years of dating, your romantic relationship holds about a 25% importance to life activities. Another 25% goes to family and such obligations, and about 50% to friends and activities. Of course, oftentimes the boyfriend/girlfriend is also a member of your friendship and activity portfolio, therefore easily attended to when everyone "hangs out" at the Super America parking lot following the football game. I sincerely hope you had a cooler place to hang out at than I. It's a harmonic and proportionate lifestyle, and should the relationship come to end, you've got a heck of a lot other stuff going on to nurture your pain or glee.
Things get a bit different in your later years. You end up in relationships because that person is somebody you can stand at long lengths and want to bring into the other 75% of your life. If you form a close relationship, you no longer have separate turfs- everything melds into the great relationship melting pot and soon he's got every single one of your family members and friends as his Facebook friend. There's no property lines there people, Facebook is forever. So you must wonder to yourself, "What will my life look like if we break up?"
Not only will you miss this person, considering again that you actually like the person you are in relations with, but you have to abstract yourself from every little portion of your melting pot. Then what's left? A happy hour with old coworkers here, a shopping day with your friends there, and the very once and awhile coffee date. Your own family is mad at you, shaking their heads and continually telling you how much they liked so-and-so and why do you have to be so picky comments. Man, its no easy task. Heartbreak and extraction surgery bundled up into one big break-up ball to be followed be reconstructive scheduling surgery.
I'm going to have to agree with you there Miss Clarkson, keep up the great lyrical work.
