Its been 4 months and I just want her to know how I feel after she broke up with me

So do you know What Ex means?

At least you decide to tell her about your feelings, she never will know.
or does she is a mind-reader?

just do so... unless if she totally hates u but if u guys r still friends then do so

She broke up with you
She does not care how you feel ?

Heck no, just forget about her and move on.

Obviously, the break-up is still bothering you. I suggest you write her a letter listing all your feelings then don't mail it. What is your motive for writing this letter? Do you think it might bring you together again?

I'm not suggesting that writing a letter would be bad, but think of why you want her to know how you felt about breaking up with her. That's why I suggest you do two things:

1. Write the letter and don't mail it.
2. Think about your motivation for sending it. If you still want to send it, okay, but make sure the reason for doing so isn't to try to win her back.

Good luck.
