For a while, things are begining to look dull and boring or probably she does not connect anymore. Here are things you should do to stay together.1. Share a Chuckle In the language of love, laughter is key. Reminiscing about inside jokes can give you a bigger boost of satisfaction than recalling a laugh you had on your own, according to a study from Appalachian State University.More importantly, the shared laughter doesn’t have to stem from positive circumstances. So go ahead, laugh together about that time you face-planted on the sidewalk or made a major faux pas at a family function.2. Try a Foursome No, not that kind. We’re talking about a double date. Friendships with other couples can help solidify your relationship, finds new research from the University of Maryland. The reason: Seeing your girlfriend or wife being social at her best can make her more attractive and reveal new aspects of her personality.Interacting with another couple can also give you a model of what to strive for (the way they compliment each others sentences) or what to avoid (the way they bicker), according to the study.3. Compliment Her In the long run, small gestures mean the most, according to a 25-year study funded by the National Institute of Health. The study, which followed 373 married couples for a quarter of a century, found that those who gave affective affirmations regularly were the happiest.Try these daily: Tell your girl she looks great in her new jeans, give her a hand with the dishes, send her a middle-of-the-day sexy email, or fill up her gas tank.4. Deepen Your Conversation When was the last time you talked about anything other than the kids, work, or household chores? Knowing more about your partner in four key areas—friends, stressors, life dreams, and values—can increase overall happiness, according to a National Institute of Health study.In fact, 98 percent of the happy couples in the study said they intimately knew and understood their partners. Your move: Ask her about a happy memory from her childhood, to name the three worst songs of all time, or what her favorite movie is and why.5. Shake Things Up Playing hooky won’t always land you in hot water, so skip the same old, same old and fight your way out of a relationship rut by adding variety to a vanilla routine. Skip work and do something fun together, like going to the beach or resort.
