Am I The Asshole?

So recently I've had a falling out with a friend, we'll call him "Friend". We work together and we worked with this one guy and we'll call him "Guy". Friend is gay and he thought Guy was cute. Friend is a flirtatious guy so he'll point out to many people and coworkers who he thinks is cute and will make very suggestive comments about the men he thinks are cute. He does the same with Guy but Guy is straight. Guy and Friend do hang out but just ask friends and nothing happens between them. Guy eventually asks me for my number but nothing happens. Five months go by after nothing happens between Guy and I and nothing happens between Guy and Friend. Guy quits the job we work at and later I eventually ask Guy if he wants to hang out. We get closer then start dating. Friend finds out then decides to block me and Guy and I try figuring out what I did wrong, I ask Friend but he replies that he's not ready to tell me about his feelings. Two months go by and still nothing. Am I the asshole for dating Guy? My friends say I'm not since Guy was never available to Friend but Friend might think differently. I thought since five months went by he was over the little work crush. Friend has multiple work crushes no matter what their sexuality is. Should I have asked before I hung out with Guy? Should I break up with Guy? What do you think?
