Awoken, That's just awful. But with no D agreement there would have been no agreed-upon division of property, so can't you contact your L re: her helping herself to "extra" items, including all the photographs? I'd donate the wedding dress and other wedding items placed in the closet on purpose.
Start getting rid of whatever she didn't take that you do not want or that reminds you of her. Make the place your own. Put your stamp on it. Do what you damn well please with it!
This will make a big difference to your overall state of mind as well as emphasize when she comes over for the kids or whatever that she's out!
And, yes, you need to be more positive than that last statement. You don't know the future and you "know" none of those things for sure.
