In a relationship, especially a marriage, the two people must give one another room to breathe. While jealous can be an emotion that could damage one's self, as well as the relationship, maturity can erase any concerns. As an adult, I have learned to realize that being overly consumed with something going wrong only hurts the person at hand. That's why it's so important to give your significant other the space that they need to be who they are. If something is meant to be then it will be. If it's not meant to be there is nothing we can do to change that. So by giving the room to breathe to your mate, you will know sooner than later if things will turn out as you want them to.
