I'd say just let the stuff go for now. If it needs to come out, it will. You can slowly learn about things as you spend more time together. There may be a time he's willing to talk about it without you having to ask, or there may be a time where you can feel out the situation and ask questions as it seems appropriate.
My H seems happy to babble about what he's doing and spending money on, only he complains a lot, like I said in my thread. He talks about his friends and such, but complains about aches and pains and how much he's had to sink into his car lately, ect.
I'm so happy the Lord has given you this miracle, Dragy. Use it wisely!
