Exactly, tbh any kind of acknowledgment in regards to their comment in the context of you and her just gives it power.
If it didn’t hold some truth it wouldn’t even register emotionally for you to push back on it.
Honestly just saw that this was family but doesn’t really change anything less it was dad or mom for me.
Any kind of acknowledgment from me on the verbal level would be me questioning their behavior, helping them save face (special occasion for close fam).
“Bad day?”, “Bored today huh?”, then “we’ll talk later” after their response. In a less harsh dismissive way.
Goes for any kind of verbal response in these cases, less justifying myself, more addressing why they’re making stupid comments.
edit: family context changes it up quite a bit tbh. If its anything like i’m imagining its probably some get together where fam-extended friends are involved. Can only speak for my family but some can veer on socially awkward and say things that throw you under the bus in a “chummy” way. Not really malicious like a random person, but still unproductive to what you’re trying to do. “Watch out for this guy” type of stuff that throws you under the bus, but is really them trying to make convo
In these situs probably best to veer toward diplomacy/defusing in a way thats beneficial for all parties involved.
“Yeahh okay you’ll get your turn later”, “you jealous?”, lighthearted kind of stuff.
Honestly depends on the dynamic, your relationship, and why they were doing it. Might be overkill to socially snuff out close fam for the sake of some girl.
Id ask yourself if they were sincerely being malicious or just busting your balls.
