While the flirting question is legitimate I’m afraid it was born based on the wide spread stereotype that all italian are cheaters/players/heartbreakers and in men’s case also sexist. It’s unfortunately a trope in this fandom too,and I’ve read more than once of people saying that especially north wouldn’t work in a relationship because he’s’too flighty’. It’s very hurtful and offensive…

Thank you for your insight. 

Unfortunately, since Hetalia is based on stereotypes, you’re going to get a wide range of good and bad stereotypes that aren’t necessarily accurate in the fandom. Italians in the series are stereotyped for being good lovers, which would be contrary to being disloyal. 

In all fairness, “flighty” isn’t a completely inaccurate word to describe Veneziano’s personality outside of romantic ventures. He is irresponsible and reckless (e.g., picking fights he can’t handle, not being able to pay his bills). 

However, the big point of differentiation is that he’s always been extremely loyal to his friends. As such, he would be just as loyal in a romantic relationship. It’s also important to note that Veneziano suffers from self-esteem issues and fears abandonment, so I don’t see him being capable of doing the same to someone else.
