Should I be worried if my man is replying with fire and heart emoji to other women sexy photos?

These are not random IG models, but real women. I don't know how often he does it.

He sent Fire and heart emoji to a girl he met on a dating app before we met. They never met in person because she moved to another city, but kept her socials in case they will be in the same city one day. This was before me, but... the replies to story were recent. 2 in 2 months. not a lot but is the same woman.

OK, is it flirty what he did? Both photos were sexy. If he replied with a heart to some pasta or a dog, I wouldn't care.
