Is this classed as flirting?

Thomas

Right so I’m in a disagreement with my SO coz basically last night my mates girlfriend messaged me and said that she needed advice. I haven’t spoke to my mate in a few months but basically he’s messing her around. I don’t know my mates girlfriend that well only seen her like once but I tried to help and give advice like she asked. Anyway my SO says that this is flirting which I disagree with. I was only trying to be nice to the girl but ya know
