I've been considering asking for a raise for almost a year.
A few weeks ago I was having a coffee with Bob, a coworker who is in my team and I am in very good terms with, and I found out he felt the same way, so we agreed that we would figure out when and how to "coordinate" our requests to avoid overlapping.
This morning I received my paycheck , found it inadequate, something clicked in my mind and I stepped up and went to my boss, before even thinking about it, because I was afraid I wouldn't do it if I started overthinking it. Boss welcomed me and answered he'll come back to me in a few days and that he has been considering that too.
First thing afterward I told Bob and he freaked out. He said "you should have told me" , and I said "you're right, I am sorry". After than he's been icy all day and first thing he did after work was texting me things like "I am never ever trusting you again" and "We are never being friends again". I don't like the idea of someone I have to work with 8 hours per day being resentful toward me.
I think he's afraid that I messed up for good his chances to ask for a raise too, or that he'll look like he took the idea from me.
I know what I did wasn't nice but it wasn't done with malice. Now I am pissed off because of his excessive reaction, but I'd like to hear opinions about how to fix it - if there's anything to fix. I considered talking to the boss explaining the situation to him, but I don't think it's a good idea.
