Is he being loyal or making this up?

I’m interested in one of my ex’s friends. I don’t really consider him an ex because we dated less than a month. His friend is really sweet and a nice guy but won’t date me because I dated his friend and thinks he’s being a snake by doing this. I repeat…my ex and I only dated for less than a month and he didn’t even put in effort to try to get together so I doubt my ex would care. This guy is one of my ex newer friends and not some longtime friend but he feels like he needs to hold a strong loyalty towards my ex.
