It sounds like he still likes you a bit. Though he probably knows you're not right for him in an actual relationship he probably still feels an attraction toward you and is probably feeling a bit sad that you've left him behind. You shouldn't worry about it though because it can't be helped. He's just saying that he understands it's over between the two of you and that he hopes you'll be happy with your new guy seeing as he still cares about you. :)
I think it's quite sweet of him but at the same time I don't think he means anything by it in terms of wanting to get back together or being jealous. :)
