Every situation is different - sometimes the words are just common cliches, sometimes they are genuinely the truth - I say this in reference to the reasons he provided for the breakup.
It could very well be that he is just confused. He is still in contact with you which is an extremely positive sign. It is generally hard to just block somebody from your life when they have been such a major part of it, it appears like he is definitely struggling. I think the best thing to do here is not completely ignore him but play hard to get, be a little cold and aloof. Reply back saying 'that's nice!'. He needs a chance to miss you otherwise he will never initiate a reconciliation. If you are always around you are not giving him this opportunity to miss you, this chance to help him truly realise what his life is like without you in it.

Love is like a merry-go-round: you get all dizzy, and then you feel sick!
