@caboman957,
This is your insecurity not hers.
She was totally committed to you for 4 years. Totally. Regardless of her past. She trusted you, and loved you obviously and can have a one on one relationship.
Chances are she was used and abused and thought she was nothing, so why not play the field? She also probably has an adventurous nature and when single just goes with the flow, why? Because what she wants is love. How can I say that? Because she WAS committed to you for 4 years.
Your problem is you want a woman who is not promiscuous, just quietly because it scares the carp out of you that she will stray. Yet, quietly you reep the rewards if she trusts you that you love her, as she is playful and inviting.
But, with that, you constantly fear the worse, she will stray whilst with you after all you just admitted YOU were the one who broke up with her due to her past, not present, but past.
At that time she gave up hope huh? I mean men are men, no one wants me they don't like my past even when I spent 4 years proving I can be failthful and so the cycle was re-born.
Morals and values. How Sex and Love work.
But by arguing with her over and over and you have stated that you did, how did you teach her trust? Trust in love? You reminded her at many a moment where she came from ............
How can she gain morals and values? That comes with the belief that the person you are with loves you un-conditionally regardless of your past..... Shows you love, in the form of everything not just sex and sex is sex, but bonding and intimacy is something else.
Have a deep think.
Personally you have to get over in my opinion that a person is a person, free will and all of that. Until they are with you, at that point there should be honesty and commitment. You have to get over that we belong to ourselves, you don't own us nor can you judge us of our past.
And, you have to work out why this woman stayed faithful to you for 4 years if that isn't love what is, and why she strayed when you dumped her due to her past.
