Does True Love really last forever?

Yes, but only under the efforts of both parties involved. Like anything of real intrinsic value, true love must be respected to be preserved.
The problem with our society is that everything is so disposable. We've gotten so accustomed to the "use it until it's useless, and replace it with a new one" philosophy that we don't cherish anything anymore.
If you posses something that is as precious as true love, care for it, preserve it. Take time out to enjoy it, and above all work diligently to keep it.
Yes, true love lasts forever, when properly cared for, and given the respect it truly deserves. When we begin to invest ourselves in taking care of, and cherishing that person that has been so graciously entrusted to our care, forever is but a blink of an eye.
