I don't think silence is the solution.
I also don't think it's part of acceptance.
Accepting means being open to either answer when you inquire.
"I miss xyz with you. I would like to resume doing that. Is this something you are interested in doing too?"
The answer could be
YES! I can't believe I've been so busy.
I suppose so.
HELL NO I am so sick of that.
Acceptance means understanding and being ok with the fact that any of these answers could follow your question.
It's not a matter of saying YOU are ok with the situation. But-if you aren't ok with the situation-then it's on you to move on.
If you bring it up and you both want a change in simiarl directions, GREAT!
