How do u know when to break up with a girl?

i have a girlfriend and thinks are going really slow so how do i know to break up with her and how to do it nicely so i wont hurt her feelings too bad?How do u know when to break up with a girl?
you know when:


-you think of other girls more than you think of her


-you don't have much fun with her


-when you argue 80% of the time


-when you feel like breaking up


-when you think other girls are better than her


-when you no longer have arguements but have fights





Ways to break up:


-do it in person, yeah it's harder but atleast she knows you had the strength to tell her to her face.


-tell her that the relationship was great, but it seems like things are just going too slow for you.


-don't forget to look her in the eyes through all of this.


-then tell her you would still like to be friends but the relationship isn't doing well for you.





good luck. :)
