Am I really the asshole?

So there was this guy. We work together. He starts flirting saying how much he really likes me etc… After a few months of only talking and flirting, we made it official. That’s when things started switching up and I start noticing. He doesn’t really want to talk to me, he doesn’t touch me like he used to, etc…One day he asks me to borrow some money($1000) to help his sister who is sick. Turned out he used that money to go on a trip to New York. His sister didn’t even know about the money. I found this out a couple months after I had given it to him. We obviously break up. As much as I wanted to work things out with him(because I did start to fall for him which he knew because he asked) I couldn’t. I can’t have that in my life. But now it’s a little awkward at work. He’s best friends with our female supervisor. They talk all the time. She calls on him for everything, even things that don’t require 2 people. But she will talk about workers in another department doing it and it’s wrong. It came up in a recent “conversation” with her and I said that there’s favoritism in the back with them. She laughed and denied it. And now he has “the fav” written on his name tag so I know she told him about the conversation because he wasn’t there that day. In that same conversation with her, she mentioned how I always come in with an attitude not saying good morning. The not saying good morning, that’s not an attitude. That’s just me being me. Quiet and not wanting to really talk to anyone. Especially first thing in the morning. Just because I distance myself from them, doesn’t mean I have an attitude. I just want nothing to do with them anymore. I’ve tried switching departments but I got denied. So now I am just stuck there with them. Then another coworker called me a *** because he had asked me to grab an appliance down from the shelf because he doesn’t like driving the equipment. Before I could even get a word out he says never mind I will do it. And called me a ***. I have never done anything to this man. I felt he had no right to do that. Granted yes, I would of said no. But I was in the middle of doing something and because you don’t like driving is not a valid excuse to have someone else get it for you. Am I wrong in this situation or am I actually being a *** with a attitude?
