as a male, let me apologize for the ignorance he has shown, and affirm that not all males are like that. Some are mature and responsible. No one should ever play with someones emotions, especially not to this capacity.
As a Dom let me tell you I'm sorry for your ill treatment. This type of behavior is not conductive to how a REAL dom or even a REAL man would act, and I would advice you to contact his girlfriend and inform her exactly what type of scumbag shes dating.
I hate this kind of shit, gives us a bad name every time, males and doms alike.
