Put Yourself First
People who spend time bettering themselves have happier unions than those who always put their partner's needs first.
Do Go to Bed Angry
Research conducted at the University of California, San Diego, found that people often solve ongoing problems during REM.
Respect Your Relationship's Privacy
When you fight with your guy, do you vent online? Couples who post TMI photos or feud on Facebook make everyone uneasy.
Unplug After Work
"When you're always working, there's no division between the office and home, which increases stress in the relationship," says Dr. Scott Haltzman, author of The Secrets of Happily Married Women. Set a time limit for work, then unwind together before bed.
Avoid Toxic Friends
If your coupled-up pals are always fighting, it may sound irrelevant to your marriage, but research from Brown University says if your close friends split up, you are very likely to do so as well. Likewise, if your coworker, friend, or sibling parts ways with their partner, you have a 33 percent chance of following suit.
