What to do with...all this stuff?

Ok...so the break up has happened...it's official. So what do I do with all his stuff? The movies, the clothes... Yesterday I brought myself to throw away his toothbrush. That was tough. But I did it. But what about the cards, pictures...? Do I just put the in a box and shove it under my bed? Do I just throw them away? WHAT? I strongly doubt I could bring myself to throw the stuff away. And I can't do it all at once either. Throwing the toothbrush away was a big step for me. Because this break up has been hard. No lie. Not a day goes by that I don't want to call, text, email. Not one day. Whoever said it gets easier LIED. Or at least I haven't gotten to that point yet. Getting together is easy, but breaking up is hard...so hard.
