How do you know when to quit

I RECEIVED THIS IN MY EMAIL TODAY AND I WAS LIKE WHY WOULD A NORMAL PERSON WANT TO QUIT HIS/HER MARRIAGE only then that I realized that if you truly CAN'T make it work, then you need to quit.

The message read............

One of the questions I'm most frequently asked is, "How do you know when it's time to quit?"

In terms of when to give up on your marriage, here's what I recommend.

If divorcing is a consideration for you from a moral perspective, then before you go that route, try first for at least one year.

Try for at least one year!
And I mean REALLY try. You can always call it quits. You always have that option. But once you pull that trigger, it's over. No more chances. Your life will never be the same. Do you have kids? If you do, their life will never be the same.
If you end your marriage, you don't want there to be a shred of doubt in your mind. You don't ever want to look back and wonder if things could have been different. You don't want to ask yourself, "What if this...and what if that...what if I tried this...what if I did that?"
If you have to end your marriage, you want to know DEEP IN YOUR HEART that you did everything you could to make it work.

If you have to end it, you want to be able to move on with your life and into another relationship with a clear head. You want to come to a place of healthy "closure." THIS IS CRUCIAL! And to accomplish this, in my experience, it takes at least one year. I know it probably seems like a long time, but it's an investment in the rest of your life.

Here's the key point. Read carefully. It's a good investment for the rest of your life WHETHER YOUR MARRIAGE SUCCEEDS OR NOT. Obviously, it's a good investment if you turn your marriage around. But if you don't, it will NOT have been a wasted year. It will have been the most important thing you could have done with that year because of how your effort will impact the rest of your life AND (if it comes to this) YOUR NEXT RELATIONSHIP.
I have seen too many cases of spouses ending their marriage prematurely, and as result of not reach.
