Not to mention, let's switch gender roles and topics for a second.
What if SHE was nagging HIM to give his passwords over to her so SHE could check his phone? Then you guys would be all about how you 'gotta put your woman in CHECK.'
let's take the topic down a notch, what of SHE was constantly nagging HIM about introducing her to his parents, and he wasn't comfortable with that? Again, she would be the villain and you guys would craft creative responses of how to get standards and boundaries and put HER in check, go NC, etc.
But when the shoe is in the other foot and it's SHE who is saying "yep, I did that but I didn't like it, and I don't plan on doing it again" it's all about how SHE is at fault?
Not to mention, the idea that some of you wild jump to this place that she was actually "taunting" him by disclosing her true sexual history, that she did it "by design" to fvck with him......
This is concerning. If you really believe that this would be the reason a woman would tell you her sexual history, and then withhold the same activities from you, to taunt you, that says a LOT about how the women you have dated have been completely sub par and you really need to learn to screen for better quality women.
From my perspective, she probably engaged in those activities BECAUSE she had lower self esteem before and was afraid to lose the guy. Now she's decided to raise her standards and honor herself. No shame there.
