If you eventually break up with someone, was it ever true love?

Keep in mind that as I write this I have never had a break-up. I think that there could have been true love for one of the parties and not the other.

I think there are situations where someone can truly be in love with someone and then the other leaves them heart-broken after a change in their own personal situation. There could be a situation to happen when you have to say to your true love that, I have to move one and it is in your best interest, and I think too much of you to carry an unhappy you around, go follow your own dreams.
