Skip the laundry or go to a laundromat. It’s ok not to go to the house, but if you did I’ll bet he won’t be there. Just assume that he knows since he saw the pictures first. If he hasn’t talked to you about this already, he isn’t planning to. You’re both in the same boat here so he expects that you won’t talk about it with anyone, just like how he won’t talk about you.

If you want to do the right thing, you own up to it and let your mom know what’s going on. But this won’t be easy. Things are going to be awkward for a while, and maybe you should all go to family therapy to help. By the by, I don’t think you need to talk to your dad. You both know what the other person would yell at you for-you both know what was wrong about this-so I think it’s more a matter of figuring out how to rebuild your trust.
