ShOw me the meaning Of being lOnley...

I want your opinion: does the love really exist? Or is it just a habit? And I'm not talking about falling in love, because I know that's real - it's the most beautiful feeling on the world. I'm talking about the feeling that comes after, for example, one, two, five months. When you feel you can't live without him (or her) , you miss him when he's gone and you count minutes until the next time you'll see him. You say it's true love.
But then you brake up with that person and, after week or two, you feel you miss him, but not on the way you thought you will. You miss having someone who will call you every night before you go to bed just to say "sweet dreams", someone who will take you out every Friday night, someone who will always have time for you...and not his smile, jokes, perfume, the way he looks at you or the way he says "I love you"...Honestly, I don't think that's love anymore. I think that's just a habit.
Please, correct me if I'm wrong.
