Some people, of any gender, do things they regret later. The conscience nags &/or maturity sets in -- then he/she decides to reinvent into a better person. As they say, it is never too late to re-invent one's self -- and we should respect that. Meaning, we should not demand to have full knowledge of anybody's blotter sheet. If you really love the person "as-is, now" -- suck it up. Although, the beloved should reveal critical details (when it is reasonably time to share) like: I had a vasectomy, irreversible; or: I have terminal cancer; or, I am married; or, I have x children... that kind of info. But as to how many he/she effed and other details thereof -- if the person is not the eff-and-tell type. -- why should you insist on knowing? That part of his/her life eh gusto nya nang leave in the past -- IMO, it has no relevance to how much & how you are loved now.
I am kinda confused with your cuento.
1st: You insist it is an issue of trust.
Ok, you asked & she didn't give truthful details. Yes, you are right in feeling hurt that she lied. You are very peeved/hurt that on more than 1 occasion, she lied and convinced you -- only for you to learn "the truth" from someone else. So, it is less of a trust issue, but more of a pride issue there? coz she was able to convince you of her untruthful answer until binuko ng iba. Na-convince ka nya, she played you.
But can you really 100percent say she lied to you with a straight face 100percent? Iba din kasi perception/extent of knowledge ng ibang tao, lalo na kung tsismosa, just saying. And, curious lang ako: why are you doing small talk with others about her personal past?
2nd: You insist you hate her lying, that it is not an issue about her past. Fine, who needs a congenital liar in one's life nga naman.
BUT somewhere in your posts you say it's as if you love this person who is now like a stranger to you. Is it the lying, or are you referring to her past adventures/persona? Ang gets ko kasi eh you love this image of her, eh shukz! may colorful hidden past pala. So you gotta decide if it's just the image ( you have in your mind of her) you are enamored with -- coz well, true love means you accept the whole person warts & all. I mean, who ba falls in love with a person whose past & present is out there like an open book? Di ba everyone is like an onion with many layers, & the layers are gradually peeled off? No one falls in love with Perfection, IMO -- coz there is no perfect person --That Perfection is just an image/blueprint. We fall in love with 1/2/a bunch of positive attributes (in the beloved). that we deem are important to us -- so, can you go back now and recall what it was in her you fell in love with? Andon pa ba yon?? If andon pa, why are you complicating matters?
3rd issue: Her trust in you. I kinda feel her situation. Why do people lie? Because the listener cannot accept the truth peacefully. Same same, que bata nagsisinungaling sa mom or a philanderer to his wife. The listener will not accept the truth peacefully & just let it go -- May reaction yan, usually unpleasant.
I am not saying the reaction is unmerited (Aba, some truth-sayers eh -- deserve mabaril agad on the spot. Hahaha)
Maybe sa kilatis nya sa yo eh -- tingin nya you cannot handle colorful or graphic details. She perhaps thought you needed PG13, something like that.
Maybe, she does not trust you will not throw in her face what is irrelevant to you (coz it was before Your Time) during a fight; or that you will "extrapolate". Na como she cheated on her man before, she will do the same thing to you.
And, well, the ability to trust is a very personal thing. Her ability is the product of her past & where she's coming from ika nga. Lalo na if you have been reacting negatively to details of her colorful past -- she will hide it more. It's not you, it's her comfort level -- it's her call to tell you what she thinks you are capable of handling.
TRUST is like an eraser: it gets smaller with each mistake.
TRUST is 2-way too, JOJO. You have trust issues with her, she has trust issues with you too.
IMO, better you focus on the reality of who she is NOW, and the reality of what you love in her.
IF you CAN STILL SEE & VALUE what you fell in love with in her that is still there in her now. -- that should clarify your confusion now. Intense Interrogation will not strengthen you relationship coz True Love is a leap of faith. (Faith ha, hindi chain of kagagahan. But haynaku, many of us women, get tied by the chain, hahaha.)
BUT if you are the type of person who does not have a strong heart to love a person as-is, where-is-now; and you do not possess the confidence to love & be loved -- best you end this pseudo-love of yours soonest. Why? Kasi you will be plagued by mamaws all your life together. That, IMO, is your core issue: the mamaws.
