you want to involve him in your process and or healing.

are you still interested in him?

how'd you find out about his "trust" issues?

it seems like a set up for trouble to enter into a sexual relationship with no boundaries and parameters if someone is known to have trust issues

even don't ask and don't tell has to have clear lines

if you guys are don't ask don't tell, keep it that way.

seek out support from others

that is unless you want to think of him as possibly being much more than what he was when you reconnect.

It may seem difficult to not discuss at first but it will get easier depending on if you guys have issues or not because of the separation.
