You sense that there is something not right with your relationship but you cannot quite identify what exactly is wrong. What you know for sure is that you and your spouse do not seem to be as loving as you used to be but whatever had happened to that love? The first thing you need to do is to have an open communication with your spouse.
As yourself when was the last time you really had a heart-to-heart talk with your spouse? It is very important for couples to share their dreams and emotions with each other, so if both of you seem to be behaving like strangers, then it is high time you take some actions in saving your marriage before it is too late.
