Tiasmum, it is totaly the right thing to share if you feel you want to. He might not feel its right for him but maybe its right for you.
When I first came to MN, I was struggling a bit with the way my life was. I have said it before....... I needed friends who were there anytime of day or night to hold me up and tell me it would be ok, empathise with the stuff that wasn't working, and I needed the anonymity. I didn't have anyone in RL who could fit that.
It marked the beginning of me getting on top of things again. I admitted to myself I had PND which was a big step. Being able to say it and still be accepted meant a lot. Until then, I couldn't even admit it to myself.
Now, I am much, much stronger, I even managed to get myself to counselling (from MN encouragement) which was a big step for me but so needed and so worth it.
Now, I have wonderful friends here who have helped much more than they will ever know. I have never met any of them.
Now, instead of leaning on everyone, I can be supportive when I see someone else falling apart.
Maybe your DH doesn't need this type of support but I hope he is open to see that we are not a bunch of computer geeks who lie........we are a supportive bundle of parents who share and try to help each other along the way.
I have two friends on the daily multiples chat thread who have each lost children. They struggle and they help and they cry and they laugh. We just do it together. We each have our stories.
I've blabbed enough.
If you need us, we are here.
