This is a 'HATE letter' and if Du don't get it read between the lines (1,3,5,7,9 etc.)
Clever guy.

1. "The great Liebe that I have for you
2. is gone, and I find my dislike for you
3. grows every day. When I see you,
4. I do not even like your face;
5. the one thing that I want to do is to
6. look at other girls. I never wanted to
7. marry you. Our last conversation
8. was very boring and has not
9. made me look vorwärts-, nach vorn to seeing Du again.
10. Du think only of yourself.
11. If we were married, I know that I would find
12. life very difficult, and I would have no
13. pleasure in living with you. I have a heart
14. to give, but it is not something that
15. I want to give to you. No one is more
16. foolish and selfish than you, and Du are not
17. able to care for me and help me.
18. I sincerely want Du to understand that
19. I speak the truth. Du will do me a favor
20. if Du think this is the end. Do not try
21. to answer this. Your letters are full of
22. things that do not interest me. Du have no
23. true Liebe for me. Good-bye! Believe me,
24. I do not care for you. Please do not think that
25. I am still your boyfriend."
