focus on changing. even if it takes a while. focus on changing for now, and becoming a better person. find someone new when your ready and when youve grown. you made a fucked up mistake, and your facing the consequences. now make the action to change cause it aint the end. be a better person for a new potential partner.
its natural to feel sad about your past relationships but you know you need to let them go and find happiness. i hope the both of them are doing ok. and as long as your making an effort to change you’ll be ok too. you can be better mate.
