A marriage is always changing an evolving and its so important to stay well connected to each other. Its easy to become distracted or preoccupied but in doing so it begins to develop cracks in the relationship. You need to listen to your spouse and also listen to what he or she might not be saying. Pay attention to the moods and vibes of the relationship. As soon as you feel things aren’t right then it is essential to begin talking to each other without any distractions. If things still do not improve then it is critical that you both attend marriage counseling.
Its much easier putting the time and energy and cost into each other in an effort to salvage your marriage than it is going through a divorce and starting all over with someone else only to realize that they will have a whole set of other problems and downfalls that your spouse did not. The grass is not greener on the other side. Sure someone else might have that 15% that your spouse does not have however that new individual will be missing a lot of good qualities your spouse had.
