Well then fast forward to around March and I noticed that he was getting quite distant from me. He did have a lot going on since he and his ex were finally going their separate ways and everything which was hard for the both of them. But then later on at around May I ended up finding out that he had been hanging out with another girl we work and then I later found out that they had hung out even before he started hanging out with me but things fell apart and then she ended up getting a boyfriend.
I confronted him about it once I found out and his only response was that we weren't dating which was true. He then said he wants to further our friendship but is skeptical due to how I reacted. He wants to be friends and we have hung out once since then but now he ignores me and she ignores me too. I hate seeing them flirt at work and I don't know how to handle it. He also states he's not sure what he wants from a relationship and is now looking at things long term.
I don't know what to do any help/advice is appreciated!
