uno - i don't know the full back story so apologies if none of this makes sense. And this is to your earlier post.
DP and I had problems (there was a period of him talking on a dating website in the first 6 months odd of our relationship and a little problem with alcohol that we don't like to dwell on
).
Anyway, it was a scab that I picked constantly, drove myself mad. He just didn't understand my need to talk about it, he just avoided it each time because in his eyes it would lead to arguments. Which it did, frequently 
The more he ignored and avoided the more obsessed i became. Eventually (and only recently) we had a really honest conversation where I said that I needed him to come to me not it always being me that brought things up. He was always like an ostrich, the minute he thought I was feeling bad about things he'd ignore it and try to run away from any conversation.
So, now what has actually happened is that if something comes up that reminds me of what happened (like a jk cheating episode!!) he sees me go quiet and he'll say 'this is upsetting you isn't it? Do you want to talk about it?' or 'This is bringing back bad feelings for me because of x, y, z'
It changes everything (well it did for us) because then its not the big elephant in the room and also you don't feel like a nag because its always you 'raking up old ground'. In fact he just said to me 'Are you ok? Are you sure?' because I was being a bit quiet tonight.
What I'm trying to say is that I understand how you feel when your dh isn't bringing up things or discussing things, makes you resentful and annoyed and hurt.
The way I finally got through to dp was to say 'yes i might shout, we might row, but if we don't talk about things we WILL DEFINITELY split up'. Once he realised we could talk and row but actually it was ok in the end, he felt safe enough to start starting conversations.
Seeing your later posts it definitely sounds like a child-adult dynamic. Drama queen to the max (and thats coming from me!)
Again this may stem from him being ill. I know when dp looked after me when i was ill i got quite infantilised after a while, its easy to fall in to.
So, none of that probably helped but I hope it helps to know that I'm thinking of you. x
