Hi r3d...
I've chatted with you before on occassion;- hope dd is ok, and you too! First thing, it's great that you are thinking about yr DH's feelings, and recognising that some of us find it harder than others. I had similar issues with DP-although I was less than sympathetic, his answer was heavy drinking which resulted in us splitting up; not the fairytale scenario but, nevertheless we're all friends now.
As for counselling,I got some, and I found it was helpful. I cried a lot, but at least it was an outlet. I got some free counselling from mind paid for by our 'sure start' people, but I did find that when DS got to school age, they couldn't help anymore. Where I live (Hackney) there's a carer's centre, which offers counselling; You can ask your GP too, although you might have to wait.
Now, with my DS about the same age as your DD I would talk to our community paed, the local parents' support groups, or even the local Child and adolescent mental health service (CAMHS) who might advise you aboiut counselling.
Your DH might prefer a parent support group, or just going out for a few beers with someone with similar experiences...
is there anyone on here living near you?
good luck!
