Oh hun

Sometimes boys just aren't very good at explaining themselves.

Maybe he just needs a little time. I realise that it may be hard for you to understand but as someone who has been in a position where their DH said "enough" and wouldn't discuss the topic for months on end he probably just isn't expressing himself very well.

I don't know your personal circumstances but I can guess, given where this is being posted. Please try to remember that people grieve loss differently, and it is harder to understand other people's grieving process if it doesn't fit the same timeframe as your own.

Maybe give him a little bit of time and try to put TTCing out of your mind (and out of the topics for discussion) for a little while and give him some space to come around to the idea again.

Good luck
