These types of getaways are more common for younger people who want to hold onto some single traits. A lot of people worry about keeping their self identity when in a relationship/marriage.
It's one thing to go to a play, have lunch, or attend a sporting event. However when it comes to hitting the nightclubs, weekend getaways, or week long exotic tropical vacations..etc
You could be playing with fire.
It's here where the person who wants the "getaway" time from their spouse will say there is a "Trust" issue. Honestly it may not have anything to do with trust but simply a difference in the idea of what marriage should be.
There is no "right" or "wrong".
There is only "agree" or "disagree".
Life is much easier when you marry someone who wants what you want. If you envision a marriage where there will be "boy's/girl's night out" and separate vacations it's best to have that discussion before saying "I do." Trying to change someone's way of thinking after the fact can cause frustration and resentment.
Marriage is less about YOU & ME and more about US & WE.
If you still feel a strong need to "party" with the boys or girls there is a good chance you are not ready to settle down yet.
