The Urban Dictionary defines unconditional love as:
"To love somebody with no conditions or circumstances: to love completely."
It's very important that children, your family and your spouse feel unconditional love. Because when they don't, it creates a really bad situation and impacts confidence, freedom to be one's self, along with a variety of feelings that are not needed or helpful with having a healthy relationship. Give and show unconditional love to those you truly love, after all it's one of the best gifts you can give, it's the right thing to do, and it models the way for others.
