Fall Back

How do you know when it's time to fall back from a relationship?

Too many times I hear people say they didn't end a situation when they should have...earlier on...before the other person cheated...before the other person admitted they were in love with their best friend (the same person you always suspected)...before the secret love letters found while doing laundry...before the missing condoms...before the 3am phone calls from "only friends"...before the coming home late or not coming home at all...before the lying began...before the snooping began...before the trust faded...before the person broke your heart.

Before all of this happens there are always signs that we should fall back and let it go...but why don't we? Why don't we use the common sense we were born with and fall back and then move on? Why can we advise our friends but when we find ourselves in the same situation we can't take our own advice? Do we stay and try to make it last because the thought of that person being with someone else or already having you replaced is more than your heart can bear?
