We have all heard it, and truthfully most of us have probably been guilty of saying the classic line: "I just don't need a relationship right now".
This is one of the oldest cop-outs in the books. You talk to someone for a couple of weeks and realize it isn't going to work; so instead of being honest and telling them that you truthfully just don't see this relationship progressing, you tell them you aren't ready for a relationship.
The naive person wonders, well when will they be ready? The sad truth is they wouldn't be ready, at least not for you. The fact is that they might be ready for a relationship. but they aren't ready for one with you.
This stings far deeper than just admitting when you don't have chemistry with someone like you thought you would. That doesn't hurt to the core.
When they aren't ready for a relationship with you, you wonder who will make them ready? You will wonder, what she has that you don't? When she makes her Instagram debut, you'll question every thing about her, wondering what she has that was different than you.
He doesn't realize the damage being caused. You don't know rather to wait or rather to move on. The back of your mind tells you just to wait around; he'll come around. Painfully, you start to see the issue. You realize it was you he didn't want.
So next time, you decide you "aren't ready for a relationship" find another excuse. Trying telling the truth instead.
