You've said a few times in this thread something along the lines of "I don't know the rules". What rules?
Polyamory isn't an all or nothing thing. It isn't something that has a guidebook to follow. What works for one person/couple/triad/whatever isn't going to work for all.
The rules are the ones YOU make, hopefully in conjunction with Jason and Michael, that make the situation least painful and easiest for the three of you to work within.
That said, I have to agree with Marcus that to me, your situation doesn't sound particularly healthy relationship-wise. But you're the only one who can decide whether it's a situation that's going to work for you and whether you're willing to accept two men who refuse to communicate, one of whom keeps you hidden because he's afraid of what his family will do.
