I'm a terrible boyfriend..
I have a girlfriend, we really like each other. And I'm graduating this year from high school. We've been dating awhile now, and she loves me. And I love her. But I've been cheating on her for the last month. And it's spur of the moment things. And now I feel like **. And she doesn't deserve any of this. I feel like I should tell her. But I'm scared to lose her. And I really do not want that at all. I just don't know what to do, I'm scared and can't talk to her. I feel so bad about all of this. If you read this, I love you. And really am sorry. Hope I get the ** to tell you soon and I hope you still love me.
Don't worry about it. She's not the one you end up with anyway
Don't ever tell her if you care about her - it's the cowardly thing to do. It'll ease your conscience but hurt her in a terrible way. But break up with her because there are obviously issues that caused you to cheat.
