Which if these is the worst red flag for a romantic partnership?

This is a real guy who says he has been sleeping with the same girl for 10 years and I actually do believe him, but I do not think he would be considered faithful. Feel free to share your thoughts

He has a gambling problem
He has a porn addiction
He talks to his friends about how he would fuck the shit out of other women
He says he can't cheat because his wife provides for him
He buys another girl flowers
Honestly none of these options says he is unfaithful
Honestly multiple options are just as bad
