A lot of that was done subconsciously to convince himself that you wasn't worth being around and to make it seems its all your fault. Its pretty sad and pathetic actually don't let it bother you. Also it shows his true colors of being a dick. It actually is a good thing. While what he says stings right now you won't miss him, think about him much and for sure won't take him back under any circumstances. You got a clean break and won't be on here 5 months from now talking about my ex and I are friends with benefits and hanging out blah blah blah. You saw what he was doing a mile away and you should be counting your lucky stars you don't have to deal with someone so immature and insecure.

because breaking up with you in a nice way would make him feel guilty for wasting your time and like it was his fault (which it is), making something up to start an argument makes him feel like he can pretend it was because of the fight and because of you not because he's afraid of commitment or was just stringing you along till something better came along.
youve got a healthy outlook on this, dont go back to him if he comes begging for another chance. you already gave him one once and he just did it again to you so he's likely to keep on doing it in the future and who wants to be with someone theyre not sure is going to break up and abandon them as soon as they can't be bothered with the relationship again
