I certainly wouldn't choose your ", ex" A guy who'd leave his girlfriend for you can never be trusted. At the back of your mind you'll always wonder or worry if he'll do the same to you. He's shown his potential.
Plus , you said his ex gifriend , who he left for you , is your friend. That's a friendship boundary that shouldn't be crossed. I'd never even put a girl who I didn't know personally in such a hurtful situation.
I'd never put myself in a position where I broke another girls heart. I'd cut contact with him. I wouldn't want a boyfriend either who'd hurt his " girlfriend" this way
