about a year ago me and my gf started to fight a lot. i had issues with controlling my anger and i said things to her and her parents that i deeply regret. her parents are very hard headed and ive tried several times to apologize for my actions and my words. still no dice. i really do not know how to fix this relationship, but i need to. ive asked them what i have to do and they basically said they will never forget what i did. in order for my gf and i's relationship to progress any further i need to fix this. does anyone have any ideas or been in this situation before?
