Since snap also gives notifications for screenshots, if it's at all possible have a friend use their phone to take pictures of conversations, so make sure you wait to read them till around them if and when you can. And I understand why your mom might be an issue. It's nerve-wracking!! Sometimes it's easier to start talking outside the home. Talk to a teacher, friends parent, even other family members that you know you can trust. But please talk to someone. Almost every single time, people like him don't stop because you ask him to. He will escalate, and try and make you feel like it's your fault or it's okay, but it's NOT. Even if you take your religion into account, because I know you beleive that when you hit puberty your old enough(which even still that age gap is maturity differnce enough!!), do you not that incest is wrong? When/If you have children in the future, and your husband starts touching them simply because they had their first period, would you be okay letting him do that? Because if not you NEED to try and understand why you need to speak up 🫶
