My ex texted me... what should I do?

My ex broke up with me three weeks ago and then a few nights ago, he texted me in the middle of the night apologizing because he couldn't find a couple shirts that I'd asked him to find and mail to me the day of the breakup. I guess I'm just looking for some ideas on what it means/why he texted me and what I should do about it. I would like to be friends again in the future, but I'm not sure I'm ready for that right now... We'd dated for almost a year and been friends for four years prior and he ended it (I think?) because he'd going to college in a month and he's nervous and can't handle a relationship now. He's also diagnosed with depression and it seems like he's in a low point. Our relationship was semi long-distance, which was hard for him. At the same time, he was the guy who told me he loved me after we dated for two weeks and had already named our future children and thought that far ahead, so it's a bit confusing.
