Why wouldn’t he answer my question?

"when someone shows you who they are, believe them". He doesn't value you. Please know how special you are. He can't answer because he doesn't have the depth to. And that's ok. Everyone has issues. Just walk away. He's not your person.

whether he did cry or not there are reasons to not want to say. if he didn't cry but cares he might not want to say "no, I didn't cry" because it makes him look insensitive but if he did cry he might not want to say because many girl are turned off by a guy who cries so we tend to not want to show that side. I was litterally told by an ex that after seeing me cry once she was instantly turn off .

He's a player

Guys don't have the closure problem if he answers you will only have more questions or want to change.

Because it is very easy not to answer when texting.

Really, why does it even matter to you to know.

Move on.

He sounds like a narcissist, I'm glad you're no longer with him.
