Could I just offer another perspective? Please don't flame me anyone . .
Victoria, your fella is probably feeling very inadequate and may be blaming himself for not making you pregnant. Men are generally rubbish at acknowledging any bad feelings and are far more likely to retreat in their 'cave' and shut out the world. Don't get me wrong, I am totally on your side - you deserve so much more from him. I'm just concerned that, if you confronted him in the 'wrong' way (maybe when either you or him are feeling particularly low and tensions are running high) then he may simply retreat further. This is where Purdey's suggestion trying Relate would come in.
There must be a good bond between you, as you have been together for so long. But, as others have said, you need to be at your strongest before having children. I heard someone say once that "a baby is not a sticking plaster for all the wounds in your relationship, it is a magnifying glass." This is sooo true. Dh and I are very lucky to have a good marriage but we have never sniped and bickered at one another so much since dd was born.
I really hope you can work something out and be happy again. Sod the hugs, have some
and
