It is responsible to recognize that you both feel how you feel, talk about that, and understand that is subject to change.
Just because he is "ok" with it now does not mean he will always feel that way. And it does not mean that he won't always feel ok with it either. And your emotions too may get easier to deal with. If you need help - get help. If he needs help - support him in his healing. I would not tell him he needs help or how to feel, just listen to how he feels.
All I am saying is everything is so fresh and raw don't think you have to do anything but live in the moment. I think you really love each other so just hang on to that for now.
I bid you Peace.
The time is always NOW. Breath In. Breath Out. Move On.
