Words don't exactly mean *nothing.* Negative words, for example, aren't cancelled out by positive actions. But the point to remember is, "Words & actions go hand in hand." And when it comes to positive words, actions speak louder.
Stop try to change someone who doesn't what to change. Stop giving chances to someone who abuse your forgiveness . Stop walking back to the place where you heart run from . Stop trusting their words and ignoring their actions. Stop breaking you own heart.
