Phat, how many people do you have in your social circle that you would call a 'friend' when they pay for something and then hold that over your head like an axe?
Maybe in the past this person has done things for you, and you can get he's urging you to do more yourself, sure (Which is happening btw, it had been happening before Trump claimed he was the one that caused Europe to work up to a % of budget spending on military), but right now, that 'friend' is not only pissing on you because they gave money before.
They're telling you that your worst enemy, is going to be their new best friend, and whatever shit they leave behind together, YOU have to pick up, you have to fix, and he's giving you the middle finger.
Would you call that person a friend still because you have a history together?
I've broken off with friends in the past for less than that.
