Sensitive cancer friend is mad at me will he ever get over it how can i apologize?

I am a Cancer too. For Cancers it is very hard to forgive someone and to forget an abuse. We are very sensitive so even a little harsh word toward us is very painful for us. Never forgive nor forgot. If you want to apologize you might say "I am very sorry that I have done................... Please forgive me. I will never do that again. I was wrong I am sorry. Lets be friends again." I am pretty sure that when he will hear that he will forgive you. Good luck!
