I am not sure exactly what the word would be. Perhaps just moving on to different history in your life. Another chapter maybe. I think that if you are still going to bed with your spouses picture in your arms when you are dating someone else maybe you are not ready for another spouse, but your spouse is part of your history and there is no denying that. I don't see anything wrong with keeping a spot in your home for pictures etc. because that is your life. Especially if you have children. I think another spouse would understand that. And they would keep their photos or mementos as well, or not if it were through divorce.
How would it feel, I think would depend on factors of your life. I think it would feel wonderful but different than before. There are different kinds of loves, but real just the same. I think it is alright to laugh again and love again. And that your new spouse will bring different dynamics to your life and you will feel the closeness again just in a different way. After all you are a different person now too.
I am not sure how to express the way I feel about it but, I think God will bring you what you need, He knows you better than anyone. I don't know if any of this helps, maybe I will think of some better words. This place is a peaceful place to come and rest here, and when you need us we will be here. Or just stop by for a laugh or two! Keep the faith and be good to yourself!
Take care ~ Jane
