If a guy says to you when you ask him why he’s single ‘well I’m really happy why would I change my life’ ?

Is this a red flag? We had a discussion about dating and when I asked him about why someone like him would be single (he’s literally gorgeous , kind, intelligent …. ) he said well why would I change my life when I’m so happy..

Should I give him a wide berth? Thanks

He’s really flirty with me though - had a tough breakup so maybe that’s why?
