I just want y’all’s opinions?

So I have a coworker at work he’s younger than me not going to say by how much but it’s enough (he’s legal) but anyways at work he used to pick on me and make sexual jokes, just stuff that a young guy his age would do. But anyway 2 other coworkers told me that said guy liked me. Ok cool. On a side note I’ve had a situationship going on for a few years now and I told the guy that liked me that. Well based off of our convo it was clear he just wanted one thing. I told him I couldn’t because of the guy that I’ve been dealing like I know if I did it I’d lose him and I wasn’t ready for that. The only thing we did was sext that’s it nothing physical. Well at one point when we were texting, the guy who likes me asked if I live alone and I said I used to but the situation ship guy has been living with me. He sent me the facepalm emoji, I asked why and he didn’t want to say. Things were for the most part normal then he just started talking to everyone else at work and ignoring me. I asked him twice like why he was doing that and that it made me feel bad. He basically said that we aren’t obligated to talk to each other that we’re just coworkers and we can do a simple greeting and go about our day. Then I said that it was a mistake talking outside of work and we should’ve just kept it how it was, the jokes and everything at work. Then he unadded me from snap.

So is he mad because he wanted to sleep with me and because I told him no because it would upset the other guy that’s why he all a sudden doesn’t want anything to do with me? Like he did a complete 180 on me. It’s just weird being at work with all that going on, told myself I wouldn’t mess with a coworker but I think honestly I liked the attention and he’s more open sexually than the true guy so for a moment I thought I was getting a better deal.

I am not in a relationship so I didn’t cheat just wanted to make that clear.

Then I also apologized to him that we couldn’t do what he wanted to do because of my situation and that I just didn’t want it to be awkward at work and then just that he made me feel bad ignoring me and talking to everyone else at work. He had left me on opened on that message.
