Is this a good excuse?

I have a male coworker he always having loud phone calls and today I heard him say his wife rarely has sex with him if at all. And he said the excuse is most of the time, how im supposed to work afterwards? Is this a good excuse? I think BS. And my female coworker tells me he always flirt and make jokes about her vagina or sex to her he even offered a massage one time she refused. And other than that, he start treating the female coworker very bad lately it hurt her like he laugh and joke with all of us but he became so cold towards her and its hurting her a bit. Today i was with her and 2 coworker he walked past us said Good morning my female coworker didn't say it back then very later she was in the kitchen he was looking for her and saw her and ran downstairs again like whats that behaviour?

Is this a good excuse?
