But as a LBS, I would want to hear how much my husband appreciates me, cares about me and wants to be with me. I'd be curious to know what he learned about himself, what he went through and after all he has been through what he realizes about life. It would be really nice to have reassurance; That after going away as far as possible, he eventually realized where he wanted to be and where home is.
Your wife may not be ready for the details yet. But you can always let her know you'll be willing to share whatever she might want to know when she's ready. And you can always tell her you would never want to hurt her, but just want her to feel close to you and that you don't want to hold any secrets from her.
There is no arriving, ever. It is all a continual becoming.
