Hi Honey,
im glad i didt scare you totally off with my post, sorry hun..i just wanted an idea what exactly was the problem. Hmmm..you're most decidely not alone and im afraid your problem is mostly related to the 'strong silent type' syndrom. Many of us have oh's with this problem and it can manifest itself in lost of different situations.
I can very much sympethise with you having problems with your oh getting to open up. However, at some point you might have to accept that there is some places he will never go with you. He might not ever wanna look at the scan pics and he might never wanna really, talk about that period of your life ever again. This sucks majorly for you as this being your partner you obviously need to be able to talk about this thing that happened to you as a couple..but again..there might be somethings you might have to put to rest as a conversation topic between you.
He obviously seems very deeply wounded by this, and thats a good sign..at least he's not a total ice cube (cause believe me there are those out there too..). I would get some vino (or whatever your tipple is) and start of by saying you need to say this and that you need to know from him what he can and cannot talk/hear/know about.
You might find out its nothing..or he might surprise you with saying that with time he might feel deifferent.
This is obviously still a very open wound for you both..but as a couple you will need to find that middle ground..im not making light of this believe, but in this instance 'men really are from Mars...' as the book says. They just digest and deal with things different. the sooner you can bribe, co-erce or drag that out of him (God, i have walked in those shoes, sweetie!!) the sooner you will both heal as the loving couple that you really are and find that spark..in and out of the bedroom.
Give him space and find that middle ground honey..with time..and some tlc (as some one else wisely mentioned) you will come back from this- you will!!!
All the best, love!
