moving on after a manipulative relationship?

[David]

There are countless songs about love being blind. It is accepted in scientific circles (if that means anything!).

Don't cut yourself up for being a normal human being who was in love and couldn't see what was obvious to everybody else. It is a kind of drug and everybody knows that when you are high on something things just don't look the same.

Accept it, learn from it and learn to deal with it.

From my own experience trying to block her out doesn't work. Accept it and move it on, move it gently from your thoughts when it comes in and go on with what you are doing. With practice it will become easier. I would suggest you try meditation or mindfulness. You will find many sites on-line. One I particularly like is called headspace.com - but all of them will teach you a different way of looking at life.
