Why do do many guys in relationships lie about little things?

Is it because you don't want to deal with any confrontation? Is it a personality disorder so u don't have to communicate? Or is plain disrespect because u don't respect her?

My guy of 3 years lies about things such as when his flights arrive home, where he's headed etc. He has a problem with him feeling suffocated I'd say love avoidant to an extent. But he is always there for me, buys me nice gifts, is supportive. I don't get it. This is a full grown man. Maybe man child lol
