Is AUTHOR wrong in the post ? POST : So this is what happened: About 1.5 months ago some dude from HS (4 year ago but I have stumbled upon him a few times on town) asked me money ( I don't want to say the exact amount) to help him pay his GF's medical bills after a work related injury. I said sure why not, just make sure to pay on time. He agreed to pay me back after getting his salary ( day 20 of every month) and we went our way. 

Time went on and he did not even bother to contact me so I decided to him ask him politely if he had already been paid and if he could pay me back. He replied "hey bro, just wait a little more".  I really hated that kind of reply so I asked for a date for when he can pay me back. No answer, one day later I message him again asking the same thing, again, no answer. This really pissed me of as it was clear he did not want to give an answer (and probably pay me back) , so I send him a text saying something along the lines of " First of, I am not your Bro, and frankly i don't give a damn you Gf, it's none of my business, but I still helped pay her medical bills, so the least you could do Is have some respect and tell me when do you plan to pay me"

Am I the asshole for typing the last part?
