Although I'm sorry that you are in a position that you would prefer not to be in -- remember, it isn't the end of the world.
I was married for 10+ years before my son was born. Was it an adjustment? Of course. I had the advantage on you of desparately having wanted that child (infertility is a literal pain in the butt sometimes), but --
We did our best to integrate our son into our lives. We took him with us when we went to dinner. We got together with friends. We helped him learn to sleep in different settings, so we could go visit family out of state. (And he would fall asleep in the stroller, so if we were just visiting during the day, he could nap while we talked or whatever we were doing.)
Any time you have news that was unexpected -- be it death, pregnancy, illness -- there is a time of adjustment and adapting your thinking.
Best of luck with figuring out how to make the adjustments work for you and your dh.
