Cliche but 'still in use' break up excuses:
1. I am too young, I am not ready to commit
2. I think it is time for me to focus on my career / studies
3. It is not you; it is me!
4. You are too good for me...
5. I need to give more attention to my dog
6. You treat me too good, you are suffocating me, I need some time off
7. My grandma said I have to be with soemone who was born in the year of 'dragon'
I cant think anymore.. any suggestions?
