Have you walked so far that by the time you reach there you wanted to say there forever so you avoid going back ? Have you ever been so exhausted that you didn't have the energy to do what you had to do? Have you ever procrastinated until the stress nearly broke you? Have ever made a mistake so big, you couldn't take it back and you tried and tried and realized the more you tried, the more you struggled and the more you suffered, so you just let go, you just stop in your tracks ?
That's what falling in love with someone all wrongs for you feels like. It feels like walking to far down the wrong road and suddenly you are so tired and so far from home and you have only choice to stay at the night with someone who makes you feel safe or to crawl back alone.
