I read your other thread, and I think you've been getting some good advice, from some good people!
Just to complete the picture, are you similar in age to him? Was this prognancy expected, and hoped for, or was it a surprise (especially to him)?
I think that the little positive interaction are a good thing. Don' tmake a big deal out of them, but I think they help keep you close. I think that how you act now will help him see that you are not the cause of all the world's problems.
I think I would advise to keep wearing your rings, but don't make a big deal about it. You don't want him to see it as pressuring. But, it might help you to wear them.
Make sure you are taking good care of yourself. This is going to be a hard time, as if you didn't know!
