Backstory: My friend and I have known each other for 10 years. He is married. I, female, am a few years younger and we've become good friends. We work together.
At work, I noticed him and another female coworker touch each other in a (what I thought) inappropriate manner. Because of our environment, I texted him about what was going on/what I saw. He immediately denied that it was nothing more than "play fighting" and it wasn't what I thought I saw. I still felt uneasy so I didn't take his word right away, and *I think* that's what threw him into a cussing, beyond angry, frenzy (all through text). I apologized for questioning his integrity and his actions, because that wasn't my intention. No resolve.
Today, no words/actions were exchanged between us and he would purposely leave the same room I was in, break eye contact, turn away from me, etc.
Now this is our first BIG fight. We've had plenty of arguments, bantering, whatever. I texted him and asked if we were ignoring each other - he replied - "Just give me my space please" and that was that.
Now since this is our first big fight...I'm not sure what to do. I'm the type that is extremely proactive and I want to fix the problem immediately. I deeply regret angering him and even bringing up to him something that I thought I saw, which...I trust that he has zero sexual motives/relations with this girl or any other. I just saw this one thing and wanted to bring it to his attention...which deeply offended/angered/hurt him.
So now...do I give him his space? We don't see each other every day. Or do I make an attempt to call/text and apologize, offer a resolution, try to work things out?
