I don't think that is true. Love is hard work. It takes a lot of struggle and adjusting to the other person's needs. You go from being single, doing whatever you want, saying whatever you want, to becoming a couple. What you do and say isn't just about you anymore, you have to take the other person into consideration. The person you are with may be more sensitive, have a different sense of humor, different things get on their nerves than you. In order to make any relationship last, you have to talk and work on these things and come to happy medium.
Although Disney movies and Romance movies show love through rose colored glasses, that is not the case. Don't get me wrong, I'm making it sound like it's all bad but it's not. Nothing is better than to see a smile on their face, or to hear those three little words. It's a great feeling to know that you have someone standing beside you, no matter what happens. Someone to be your best friend, your shoulder to cry on, your help mate through this life.
So although it may not be easy, it's definitely worth the struggle. Fighting for love makes you appreciate it so much more in the end because you've worked for it and accomplished something together. A true, deep, lasting bond.
