what did I do? seriously.

So a co-worker decided to blow up at me... and I honestly have NO idea what I did wrong.

Backstory:
He is married with 2 young kids, about mid 30s, has been working here as long as me. He is continually extremely sarcastic with me. He deadpans pretty well, and uses it to continually berate me and mock me. For example, if I am looking down, he will saw aww, do you need a hug? I could call someone for you. He always calls me a slacker and says that people at work dont like me. He tries to get me to talk smack on other people we work with (which I dont, cuz I like everyone) and is always saying something about me being a bad lab tech. He says all this with a smile. And he lies a lot. He will just totally make something up to get me to believe it and then start smiling. Its been like this for months, especially since i quit school and started working at the hospital more.

Over time, I have become more resistant, basically never believing anything he says. Often I say something sarcastic back or I mock him a little bit. But seriously, the guy seeks me out just to say something mean or make fun of me.


So today I came in, did all of his controls for him because he comes in a half hour later than me, and no one else was in heme... I usually do that, regardless of who is in there. it just so happened to be him. So thats all well and go. I go about my business. i was floating so I was going back and forth between labs to whomever needed my help the most.

I walk back into chemistry, where the person has just left, and he tells me that he just reported a high glucose to a doctor that called but he wasnt sure if it was the right one. This is information that I honestly dont need to know. I look at him, say, okay, I dont know if it was the right one or not, I dont know where the person in chemistry went.

So then he says "Why do you always have to be such an asshole? I am getting really fucking tired of your sarcastic comments all the time! I am serious."

WHAT DID I DO?! Honestly, I was completely speechless. No one, NO ONE, has ever spoken to me like that. Yesterday he was all "You still love me right? No, really, its okay to tell me you love me, I know you do". (to which I said sure, whatever you say) And then today he comes in and hes like, I am seeing you way too much. To which I said, well, I saw you yesterday, but I didnt work on thursday, friday, sat, or sunday... so its been quite awhile really since I saw you.


I DONT GET IT.

So now hes avoiding me, and he hasnt spoken to me all night, and I am not going to try to make nice. Am I wrong in being completely bewildered by this? I know that I can be sarcastic, but given the way he has treated me, its the way I respond to him, and I though it was in jest. I mean, did I do anything today to warrent such an outburst? It really honestly makes me very upset, and I almost cried a few times thinking about it... and ive been thinking about it all night. Hes never blown up like that at me, though I think he has once or twice with some other lab techs that are, admittedly, difficult to work with. What in the world did I do?

Anyway, I am pretty freaked out and im trying to be angry upset, not crying upset... I have no desire to "be friends"... you just dont treat people that way. Ive blown up at one person like that in my whole life, and she deserved it for what she did to me. But... wtf?! I dont know, what do you think? Its driving me crazy... and im working with him all week. im just freaked out and dont know what to make of it all cuz I honestly was completely suprised and taken aback by him yelling at me.
