That's excellent news that H has been friendly. The card was a success! Good call on your part.
I'm sorry to hear you're a little down; I know my wife has felt the same way since we've moved so much, and never close to her family. I've always been sort of self-contained and never did much to cultivate friendships with other couples (I'm sort of like your H in that I hate to ask people for favors, though I generally don't mind doing them). That sort of isolated feeling contributed to her hopelessness and vulnerable mindset. Now may not be the time, but if you and H start working things out, I HIGHLY encourage you to help him understand that you need to build good friendships and feel connected to people close by. Eventually maybe he'll understand it's worthwhile for him to sacrifice a bit to make that happen because it will be much easier for you to be the wife and mother you want to be for him and your babies.
If need be, feel free to send him my way and I'll explain to him why it's in everyone's interest for that to happen. He may even hear those words you mentioned in a previous post: ONLY a kiss!
