text: It doesn't sound like he really wants to be in a committed relationship with you. If he was serious he wouldn't have cheated. He cheated on you not once but twice, according to him. It's probably more than that like when a cop pulls over a drunk driver and they say "oh, i only had two beers". I'd say goodbye and move on. As far as going back to being platonic friends it would probably be too awkward and painful and it won't be the same as before.
