Deb, it takes time to get through the anxiety. I still do it sometimes too, but it's getting better. The more time goes by, the more you trust and the less anxious you get. Remember to not take personally his less personal e-mails. He is getting comfortable with you. And he might be really busy. When my H is at work, he's all about work and can't be bothered with much else. I usually don't hear from him at all during the day. It's hard, but I have to remind myself that it isn't always about me. Keep letting him initiate contact for awhile. You don't want to get that clingy look to you!
I'm happy for you and your family. You've worked so hard and been through so much. I guess things really do have to get worse before they get better, huh!
