You meet a girl.
You lust after her.
You go it. Get closer. Raise heart to rates. The sexin is magnetic. You get more and more and still it doesn't feel enough. You keep going back for more. Eventually it becomes a thing you both do. All is well until you start seeing little faults, little things to be fixed, altered, made better. Soon boundries are crossed, you smothering her, asking her to change her skin, like it's a dress or a bra.

'You love the bird observing it's beautiful flight, you cage the bird to keep it close, but fail to see that caging it is stealing it's beauty of flight that made you fall in love with it in the first place'

The quote you highlighted is so very true!

Trying to change the person, is why most relationships do no last. Why does a person want to change his/her partner? Jealousy and personal insecurities. Then once you have managed to mold the person to compliment your insecurities, you wake up one morning and think to yourself "Who the fuck is this stranger in my bed?" Soon after that the break-up/divorce follows............

In answer to your title, imo wanting to change a person does not equate to love nor addiction, it is simply selfishness mixed with a very high dose of insecurity.
