We all know that one couple who has been dating for what feels like a million years. And if you know that couple then you probably have a specific opinion about them. Either you can't stand them because they need to just break up already, like every one of their pictures and tell them how cute they are, or simply don't care because it's not your life. No matter which one of these you agree with, one thing will always be true:

Their life is not yours, so quit trying to change it.

Most of the people that are critics on them are their closest friends and family and even though some of those opinions matter, not all of them do. People say stuff and they may not realize it, but it can be hurtful to the couple.

"They're always fighting! That's not healthy for a relationship."

-While it may not be 100 percent healthy, every relationship will go through arguments and fights, and that's OK.

"They are so annoying, I can never tell if they're together this week or not."

-Why does it matter if they're 'together'? They have their own lives and they are fine by themselves.

"When are they gonna break up for good?"

-Uhh again, that doesn't matter.

If you still don't get why it's none of your business, think of it from this point of view:

If they break up, what is that going to do for you? If they stay together what is that going to do for you? Nothing. It shouldn't do anything to you because you are not the one in the relationship. You aren't the one who is affected by the words. You aren't in the relationship so don't worry about them.

Personally, one of my closest friends was in a relationship like this and the amount of negativity from the people around them was immense. So many people would say rude and mean things, all because they didn't agree with their choices. So with being a best friend to her, I heard every bit of it. I heard about how her family isn't the most supportive and how they don't agree with her decision. Not only did I hear all of this when stuff was going on a while back, but I still hear it today.

People ask me all the time about what's going on with their relationship and all I will say is, "It doesn't concern you" or "It doesn't matter". What they do is for their ears only. They don't need you snooping and spying on them so just back off. If either of them wants your input on their relationship then they will ask, but for now, they don't need it.

So do yourself a favor, don't care about what's going on in their lives, don't ask and pry on every detail, and most importantly, leave them alone. It's not your relationship so don't worry about it.
