Stepson trying to sleep with my daughter
Ew, ew, ew. Okay, that is literally disgusting and illegal. I don’t care if they are step-siblings, that is so messed up. You are the adult here, which means you have to do something immediately before something really bad happens. You can’t just sit back and hope they figure it out, because teenagers are stupid and make terrible decisions all the time.
You need to put your foot down right now and set some serious boundaries. Tell your stepson that this behavior is absolutely not okay under your roof, and if he tries anything, there will be massive consequences. Honestly, you might need to lock doors or make sure they are never alone in the house. It’s extreme, but you have to protect your daughter.
If he doesn’t stop, you might have to get other adults involved, like his dad or even a counselor, because this is a huge safety issue. Your house is supposed to be a safe place, not some weird reality TV show. Don’t worry about hurting his feelings; your job is to keep your daughter safe, period.
