The truth about a girl i love

been seeing this girl in America I love her I met trough a website and we became friend .
I helped her and helped her a lot we became close and I took my time money and effort to be there for her.
when the chance came to meet I jumped booked a flight and saved like mad and flew over to America to see her when we did meet it was like an explosion of love a lust after 2 hours we where making love even though she was in a relationship with a boyfriend and I have to tell you I screwed her good.
now she gotten into BDSM scene more and is more into that than me I just found out she got a slave and doing a cock holding with some guy which breaks my heart and soul I give my all and she treats me like a nothing
