I am my girlfriends best friend and I have been cheating on her for 2 months

I haven’t been faithful for 2 months now. I am liking it. I have cheated on everyone I have ever been with but this time it feels sweeter. Because I know how much she actually cares about me. She introduced me to her parents, she introduced me to her son, and she gave me the key to her house. I am her best friend, I am her rock, I am her partner, and I am the light in her eyes. To everyone she is perfect. She has made the biggest impact on my life in the 4 years I have known her. She has been there for me through thick and thin and I have been nothing but a terrible person to her. The worst part is that I know if I get caught there will be no coming back. We will be done and I want to spend forever with her. But the way she actually cares for me makes me want to cheat more.<br><br><br>UPDATE- I deleted every comment on here because I am not here to argue with people in the comments. I am here to confess. I want to confess that I am a bad person. I am a liar. I am a cheat. And I am very sorry for what I have done to her. I do not expect to be forgiven. And I do not expect her to be okay with it. But I will stand by my choice of deleting every comment because that is not what this post is for.<br><br>I am leaving this App now.
