I think she is trying to get your trust and is feeling frustrated na so oo nga naman, if you dont end all your prying mind about her past history, maka affect ma na sa iya. Its her way of saying give me a break. If you dont trust me, if you keep dwelling on past mistakes, better pa mag break up na lang ta. Medyo sensitive cause of a past that she was not very happy with and really, i can relate to that. I do not like a guy to keep mentioning about my past and uses that for every bad trigger in your present relationship. For all you know, she was badly hurt and its a part of her life that she wants to right a wrong and it wont help if instead of supporting her, you make her go back to remember how it was with her former relationships and using that as a means or tactic of getting back at her when naa mo duha misunderstanding or problem. Kay imo man gud gi revive na iyang past na siguro she doesnt want to be reminded anymore. Its a little touchy there.
