I suggest letting go of what you can not control and focus on you, yeah I know it's not easy.
Maybe when your talking sometime and it just feels right, tell him it's ok, i want us to be honest with each other. Don't push it though, wait for the right time, when you can feel that he wants to tell you something. Make it safe and who knows.
Trust me I know about wanting to know and talk about the other person and at this point I can't think of one time that I brought it up that it didn't push my W further away and I didn't get what I wanted out of bringing it up.
