Are they back on? Who really cares? Well, you should, if you value your own relationship. What I mean is, if you have a relationship similar to this pop star duo, you need to rethink whether or not you want to invest any more time in it.
Ultimately, will Justin and Selena stay together for the long haul? I would say, absolutely not. Why? Partly because they are two young to even understand what a committed relationship even involves. But mainly, because they keep breaking up! Look around. The couples who are together 20, 30, even 50 years, have one thing in common. They don't break up and get back together...not when they were dating, and of course, not now. And they don't have a volatile relationship. That's not to say they never fight. There is a big difference between arguing once in a while and making fighting a part of your daily life.
A constant state of discourse is no good for anyone...not you, not your partner, and definitely not your relationship. So, if you find yourself fretting from day to day, or week to week about the state of your union, it won't last. It can't. Because I can almost guarantee, one or both of you is addicted to the drama. If someone asks you how your relationship is going, the answer should be a resounding "great!" If you can't say that 80 percent of the time, something is off. Rethink whether you really love him...or really love the drama.
