i broke a tiny rule but feel so bad about it

so i finally admitted to myself that this ddd/lg thing is kinda my thing. not sure how long ive known but its like only now i accept it. been thinking of ways to work it into real life because i think it could help me in some way. anyway, last night we made a rule about keeping the house clean before bed or no dessert. yeah right. i was so tired and just wanted ice cream. so i skipped vacuuming. big deal? maybe not but now im feeling super guilty. like there's this part of my brain that knows its not a huge deal and another part that feels like ive betrayed some sorta deeper contract. i know the rule isnt really about food or cleaning, its about respecting authority and doing what youre told when someone cares enough to set a limit. yeah its all just silly grownup stuff but still. now im wondering if this is normal? how do people handle these kinds of feelings in real dd/lg dynamics?
