I agree with olMUSICHnj on sth, this is my point of view:

With past times can't he mean the last experiences with other boys of the girl? They are strange, twisted and deranged because they're based on the crying lightning magic trick (and maybe with those guys it worked). He likes it in the beginning (And I love that little game you have called, crying lightning And how you like to aggravate the ice-cream and on rainy afternoons) since it's not a threat, and he's not scared by the rainy afternoons either because it looks like sth he can stand and off course he's different from the previous guys of the girl, he actually enjoys the situation. But then the magic trick becomes more and more effective and it starts rising some doubts in him (And I hate that little game you have called, crying lightning, And how you like to aggravate the icky man (?) on rainy afternoons), not because he wants to get back with her but just cause it's harder and rough at that point to dump her easily(And my thoughts got rued as you talked and chewed) and eventually also rainy afternoons become unpleasant; besides, he thought he was different from the other guys but in fact he may be not,as he shows some doubts as well (The next time that i caught my own reflection it was on its way to meet you, Thinking of excuses to postpone); he also becomes part of a group ,accused by her to be uninviting (Uninviting, but none of us impossible as everyone assumes you are), which is the one of her ex-boyfriends.
At last, I think he blames her not to be able to understand the normality of the end of a relationship since she acts like it's some kind of war not to be lost while for him it's just the usual evolution of stories, and the chance of still being friends or sth like that is ruined by her proud behaviour(With folded arms you walked aside the bench like toothache, Saw them puff your chest out like you'd never lost a war), with the subtle move of the Crying lightning which eliminates that chanche(And though i tried not to talk for the indignity of a reaction, There was not cracks to grasp, or gaps to claw.).
