In my case , I was trustworthy and trusting from start to finish while she was not trustworthy and dishonest from start to finish and way beyond . The reason it was so hard for me to get out of that unhealthy relationship was she realized she damaged her own reputation with everybody by her own misconduct that for the next 3 years she tried to convince everyone of our mutual friends and new guys she met that it was my fault we failed . She even tried to gossip that we were not engaged nor had a relationship so her best gal pals chewed her out for that . I will always believe the reason for her dishonesty was she may of been a child abuse victim way before. Several years later we encountered each other at a grocery store and had lunch. She talked. I listened . She never changed her ways for the better. We shook hands and said goodbye never to see each other again.
