I'm in a relationship with my 13th and 15th girlfriend. They're the same person we just dated twice. I've been cheated on by every girlfriend I've ever had besides one. My current girlfriend swore to me time and time again that she'd never hurt me. Given how many times my heart has been broken i should've known better. but i just wanted to believe the lie. That things will be different this time. I've never cheated on anyone nor do i ever plan to. I feel its a horrible thing. So it's 1 day after our anniversary and she calls me telling me she has something to tell me in person. I begin worrying immediately. She hangs up without saying goodbye. When we finally do meet up, she rushes into my arms, kisses me and tell me everything will be fine. Foolishly i start believing her, She starts crying before she can even get out the words, I hold her and tell her there is nothing she can say to hurt me. She then reveals to me, she has been sleeping with her abusive ex boyfriend which to my knowledge She " Hated" She bursts into tears again, Instead of even figuring out my own emotions i console her. Telling her i forgive her, lying through my very teeth. That was 3 years ago, since that day she has broken up with me to pursue her ex. only after he turned her down did she return to be with me. Broken hearted and full of stupidity i accepted her back, since then she flirts with guys letting them know how much she "Wants them". Even Now, I still don't fully trust her. I worry some parts of me can never trust her. I don't think in a relationship I'll ever be able to trust anyone..
