"I will do anything for you"
Does this include helping with homework, singing with me for extra credit in class, respecting my boundries and being emotially there for me? Apparently to you, It doesn't even come close. You promise all these things and say all these wonderful things expecting I wont remember or they wont actually happen. I am a sensitive, naive, young girl and when I hear something like that, I take it seriously. You just say it to get something from me.
Here is some news: It's not going to happen.
"I'll be faithful."
That is a big "YEAH RIGHT!" You've done it before. Why not now? How can I trust you if another person in this world doesn't trust you enough to stay with you? Good questions, I know. If you can answer any of these without saying "That was then and this is now" or "I would never do that to you", then you might be worth it but if your answer has anything to do with the "other girl" or how it was a "mistake", then you aren't. You weren't faithful by choice and that choice was yours.
