ExH and I have been separated/divorced for nearly 10 years. I bought him out of the house as part of the divorce process a year after we separated. He was invited to collect his belongings still at the house but didn't bother.
This included a whole heap of bags and boxes full of crap in the loft. In the last few years, I've been chucking a box every time I go up there and have made a lot of progress. I give them a quick check but don't go through everything. Last time I brought a box down, I saw it was full of his journals and photos from when he went travelling for a couple of years. These are all handwritten/old-school prints so irreplaceable. I chucked the lot in the bin.
The bins are being collected tomorrow and I'm having second thoughts. He was an absolute bastard to me both during and since our marriage and I don't feel like I owe him anything. OTOH, they're personal and irreplaceable. OTOOH, if he cared about them that much then he could have collected them any time in the last 10 years.
YABU - fish the box out of the bin tonight and hand it over next time he shows up to see the DC.
YANBU - don't bother.
