Why would he ask do I not trust him if we’re just friends?

Me and my ex are friends, however we work together. Today he was talking a lot with another female colleague. When I mentioned to him that he barely speaks to me in work but can talk to her loads even though he’ll stay at the bus stop with me for an hour after work, and we’ve been out a couple times outside of work. He said how me and him are always on opposite sides and that all they spoke about was colleague stuff etc customers, being tired etc and uni and he asked do I not trust him. Why did he ask this if we’re just “friends”?

I asked him if he likes her or anything because obviously where we’re friends etc so did ask out of curiosity. However he looked me in the eyes and said he doesn’t like her like that/there’s no feelings there
