Well, you could tell him that you wanna talk to a therapist and ask him to go for support. Then you can slowly work up this issue. I wouldn't blind side him by this. Maybe just suggest that you guys go for regular old relationship counselling. Many couples do that from time to time just to work on communication. Make it seem like it's no biggie and maybe he'll buy into it. It's kinda sneaky, but it sounds to me that if it's gonna get resolved between you two that this is an important thing. Hope it works. Keep us posted. Good luck.
