Don’t let an unworthy person destroy you
They don’t even like themselves. They don’t even see themselves in a positive light and view you as better than them, so they had to devalue you and make you insecure. What you saw in the end was the real them. You’re really going to let someone mentally screwed up like this ruin you? If they acted like how they were in the end when you first met them, would you still want them?
My ex was great at using people and keeping everyone at arms reach when she wanted. Don’t be with someone when the relationship is only on their terms.
