Guys.. I need a lot of help.. I'll split this all up so it can stay a bit organized, since it's long
My Girlfriend, Tanna:
Her name is Tanna, and she's the most incredible girl I've ever met.. I'm always thinking about her and how mind-blowing she is, how she's so unlike any other girl out there and so damn special that she could have any guy she could ever want. Just being with her makes me feel like the luckiest guy on the planet. Anyway, we've been together for a little over seven months now and I have loved every single minute of it. I really think she's the one, and I'm so ****ing deeply in love with her.
Her Bestfriend, Amanda:
She lives with my girlfriend, they're closer than a lot of sisters, and well, she doesn't like me very much. That's all I can really say about her considering I really don't know her much at all. We've only talked briefly a couple times.
The Problem:
Amanda told my girlfriend that I cheated on her with her, and..... She believes her..
Thing is, I didn't cheat.. AT ALL.
How it went down:
Well, last night Amanda told my girlfriend that a few months ago (I question why she's JUST saying something about it to my gf) me and her were talking on Facebook's IM chat and I gave her a bunch of hearts and shit in our conversation. WHICH IS COMPLETELY FALSE.. I swear not one bit of that is true. But of course, them being so close, my girlfriend ends up believing Amanda over me..
Now I'll be honest, when she didn't believe me, that really caught me off guard and hurt a lot.. Because we've spent a large amount of our relationship talking about how we're the only people in this ****ed up world that we can truly trust. So hearing her believe Amanda over me really made my heart sink..
After struggling to put that past me, I asked her why she would believe that.. She told me that if it was anyone else saying that, she would believe me instead, but, my girlfriend believes Amanda instead because she's like a sister to her, and that she has never lied to her before, and that Amanda swears on absolutely everything that what she's saying is true; also that unlike me, she has no reason to lie.
I tried countering that by reminding her that I've never lied to her either, and that I swear on absolutely everything that I never cheated on her. I also tried reminding her of how against cheating I am (I feel I'm more against it than most people), that if I were to ever actually cheat on her, I would come to her MYSELF and tell her about it, because the guilt of doing something like that would kill me. Not to mention, that if I ever cheated on her, I'd be so sickened with myself that I wouldn't think she should be with me, I'd be undeserving. And after saying that, I told her that's why I have no reason to lie either.. Because that would have gone against everything I stand for.. But still, unfortunately, she didn't believe me..
Eventually that night, she broke up with me.. :/ That's when things really got terrible.. The girl I love left me because she thinks I did something that I didn't even do.. IT KILLED ME.. I tried asking her to imagine what she's doing if I was actually telling the truth, and that she's destorying our entire future.. I asked her how she would feel if she found out I was telling the truth.. and she said, "I would.. feel really bad, apologize.. a lot.. Think that I'm incredibly stupid for breaking up with you, and laugh at how .. I'm crying. I wouldn't be able too forgive myself for putting you through this even for the first minute.." but then she just followed up after saying that, by saying "but you did cheat..so..".
So there I was again, pleading to her that I really didn't, but guys, no matter what I tell her, no matter how much I promise her, no matter how many things I swear on, she doesn't believe me.. And it hurts so much..
Anyway it's been like that for a while. But fast forward from last night to tonight, we were doing more talking, and you could tell that she wishes she was wrong about things (she is, she just doesn't believe it), and she wishes that she could just believe me.. But I ended up asking her to take me back, to trust me that I'm telling her the truth and have hope that I can prove it to her. So she did.
Now I'm here, asking you guys because I'm completely desperate :/ How the hell can I prove such a thing? I swear I never cheated on her, that's a fact. But she's not believing my words, and me and Amanda's conversation on facebook was on it's Instant Messanger so the conversation wasn't saved.. I really have no idea how to prove I'm being honest with her, and I really, really don't wanna lose this girl who means absolutely everything to me.. Tanna is my world and I would never, ever do something so horrible to her, and I just wish she would come to that realization.. Because I thought that was obvious before last night.. :/ So guys.. suggestions? Please.. Help me prove to her she's wrong..
Also: Side-note.
I said I didn't know much about Amanda and that's true. But I do know my girlfriend inside and out, and I know she wouldn't make her best friend some cold hearted liar. I said Amanda doesn't like me, and that's true, but I don't think she would go as far as to lie to Tanna and try to break me and her up.. I really hope that isn't the case.. I actually believe that Amanda may have me confused for someone else, or something of that sort where she THINKS I was doing something when I really wasn't and she's just completely mistaken..
Also this has apparently happened before with a couple of my girlfriend's ex's. Where they have hit on Amanda while being with her? I guess? Which completely sucks for me because now I get grouped in as just one of those guys even though I never did that.. :/
HELP, EVERYONE.. HELP.. How can I convince her?
