Why would he say/do this?

Why does a married guy say we r friends but only dms me while at work,

doesn’t message when at home even in a online game we both play he only message or voice chat if no one else is around

he also says flirty things occasionally, shares songs where he asked me to read lyrics, few weeks ago dm me a photo of him an his 2 kids.
