I think your H completely bluffed. I think he just wanted things to change and he decided this was the way to get your attention. Or maybe he really "thought" a divorce is what he wanted because nothing would ever change. Whatever his reasons for saying "I want a divorce", it's all over now. I see you guys in a reconcilation mode. Maybe I'm wrong, but he is a not a man who wants a divorce. Even if he didn't acknowledge the I love you part. He does love you.
Let him have this trip. Go a little dark at first and then follow his lead. I'm sure he'll be calling you very soon and very often.
When he gets back, keep doing your thing and let him ease back into your new marriage. You've done an amazing job. I'm so proud of you!
