This is one of the toughest times for most people... how can you prepare for this life altering experience!!?!? Most pregnancy books have chapters about what dad's go through, and ways to reassure them. Face this head on, because it only gets 10 times tougher once the baby arrives. (we have a 7 week old)
The simplest thing to do is to make plans with a father who is easy for your partner to talk to. Someone who will listen and be reassuring. Make sure he keeps talking, and try to be supportive.
This is obviously causing you a lot of stress too. Its so hard to watch someone struggle. It would be good for you to vent to some girlfriends too... because even if he is MORE stressed than you, YOU still need support, in order to be supportive to him. (whats the saying "you can't take care of others till you take care of yourself"?)
I highly recommend couples councelling too. I was very resistant to it at first (stigma of therapy), but it really gives you the proper tools to deal with problems. And it forces you to listen patiently to your partner, and find out how to improve how you communicate. And how best to support one another. I think of it as a personal trainer for relationships! Or a tune up! My husband is one of those rare man's-man who really thinks highly of councelling. We have a great councellor in the ravenswood neighborhood in chicago if you are interested, and she works on a sliding scale.
Much luck and feel free to email.
