If a woman gives off a vibe that she's lying or there is something she's hiding, is it usually true, and should I try to call her on it?

And what about when you can't really call her out on it but it just doesn't make sense?

Downgrade/keep at plate level until she improves?

Basically ltr as she's the only "plate" now that my side left for an exclusive prospect...

Honestly think that being more distant and showing less emotion will push her away and disable any possible quality future ltr if there was any.

Sex is pretty vanilla, but great and recently I started actually caring if she came so I'm sure she appreciates that.

Side note: I was still on tinder after I asked her to go out (after like 6 months of banging and dating) and she found out, so I don't blame her for doing her thing, but will definitely crush her if she keeps it up after we've settled the bs...etc
