When I broke up with my ex, it was a bit nasty as he had been cheating, anyway he left some of his stuff in my house, like clothes, tools, and bits of personal stuff. As he had left me to start a new life etc and he'd made it clear he had left, I waited a few months, then, so I could make a new start, I rounded everything up into bin bags and threw everything out. 2 years on they've now split, and he actually sent me a text saying did I still have some of his crap. I haven't answered as to be frank I don't want him to know that this is still my number and also thinking what a cheek, but also at what time scale is it considered acceptable to chuck an ex's stuff away.
