Did I strike a nerve or annoy him?

I was talking with my guy friend that I hadn't seen in like 10 years (we were friends since childhood but kinda went separate ways and lost touch) and was telling him about my ex fiance and was kinda ranting on about how guys don't want a nice, good girl, they all just want mean girls with attitudes and he went from staring right into my eyes to turning away and looking forward. To me it seemed as though he was annoyed or upset even though he was still listening but after seeing him react like that I apologized to him for venting and started talking about something else. I'm very certain he has strong feelings for me than more than just a friend, the signs are there so could it be that he was annoyed that I talked about my ex? He didn't turn away until I said "guys just want mean girls with attitudes" so not sure if I upset him. Either way, we talk and visit still so I'll take that as a good sign.
