I recently went through a horrible break up over something I did not do. It's going to sound like bullshit but hear me out. I was in another city on a job related detail assignment. Became close friends with a co-worker. The guy was engaged. On our first night out there, he meets a girl and asks if he could use my phone to get her number, since he and his fiancee shared the same account and she had access to his bill. Like a dumbass I agree. Long story short he did his thing and female had no clue the guy was engaged. He always used my phone and I would let him have the phone overnight because we were neighbors at the same hotel. Well a week before we were all going home he had me text her and tell her that he was gone and that this was my phone. I did, but to secure that she wouldn't keep calling I told her the truth and told her not to call. She was furious. I finally come home. My GF of 5 years hacks my phone account and sees phone record. While intoxicated, she calls the girl and tells her she's my GF. The girl says I'm sorry I didn't know, tells her she isn't getting involved and to never call her again. I'm automatically presumed guilty. GF won't believe me. I had the guy call her and tell her it was all him. She won't buy. By now she thinks I convinced everyone, including the other girl, to lie for me. I told her she should have just asked me and confronted me on the spot. But since she did not I have no other options. She wants me out of her life forever. I can't quit especially since I did nothing. She's the type that one strike and there's no comming back. My friends tell me to give her time and space or to just move on since she doesn't even trust me. I don't even know if I want her back but I can't go down with her thinking I betrayed her because she's the love of my life. What should I do? Please help.
