BF, The childhood and military photos are what my xh took. He left everything else behind except for his clothes, my keys to his truck and yes, a plastic Easter Egg. I still have all of the tools, etc. It was about 3 years after the divorce that he started asking for other things from my home, but I pointed out that he needed to read the divorce decree as he had gotten everything he had asked for at that time. To this day, he still continues to ask for things, but the answer is always no.
There will be times when they do act rationally and you will begin to question yourself. If your spouse has had confusion and just up and announced one day that was it...well, my money would be on mlc.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
