My fiance (dds stepdad) has left me for another woman. It turns out he was a covert narcissist and now I feel as though we have just been used and he only chose me as he saw me as vulnerable and easy to abuse. Is this the only kind of man that will ever want us? Once I am healed from this I am happy to be alone for a long period but maybe one day I would like a partner but I feel what's the point if this is going to happen again xx
