narcissistic ex boyfriend

Maybe of topic but has anyone been with narcissist before am trying to heal from that relationship

Suffering from severe ptsd aswell i thought was going mentally insane i got used,cheated on and he would yell and get mad even though i had evidence and knew the truth had three mental breakdowns in a week trying to reason with this person and when would try to leave they would stand in front of the door in tears

He lied for over two years
