How would you take this?

[Anonymous]

If your SO told you they “don’t think” they would flirt back if someone very attractive flirted with them, but they weren’t sure.

It means you're feeling very insecure and they picked up on it. They don't know how they'd react and don't want to upset you by being honest that they probably would. Light flirting is completely normal within consideration

They're being honest (that's a trait you should keep) and you're being insecure which is an unattractive trait.
