Okay?
What’s your question?
Are you looking for some advice or guidance. Are you just wanting others to sympathize with you?
It sounds unhappy that you did something that clearly upset your partner. It’s unfortunate that you were warned beforehand by being given a “rules” list, and knowingly did something that was clearly communicated as being not okay to do. Maybe it’s time to have some self-reflection on why you overstepped boundaries. Since I don’t know any details of the offense I can only say that apologizing is a good step too. Hopefully you two will be able to move past it. Perhaps relationship counseling is something you two should look into for yourselves.
