My boyfriends mom checks everything on his phone. Either at night while he asleep or while he is in the shower/bathroom, she will go on his phone without him knowing. she admits to doing it but refuses to tell him when she checks it, so by the time he wakes up/gets out of the bathroom he has no idea she has even touched his phone. she checks everything, and I mean everything. She looks through all of his recent photos/recently deleted photos, checks all of his text messages/insta and Facebook dms, she looks at his call history, search history, his notes app, and emails. Everything on his phone automatically shuts off after 9 PM even though he is required to put his phone down stairs by 7PM every night. He cannot delete his search history and incognito mode is blocked on safari because when he was 6 he searched up “naked lady’s” on the computer. He is not allowed to download any apps unless reviewed by her. once I asked if he could download <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> and her response was “that’s too inappropriate for a boy”, he is not allowed to buy any Apple Music with his own visa unless reviewed by her. He is not allowed to have more than 2 hours of screen time per day and if he goes over two hours he will not be allowed to have his phone for the next day. Every single app on his phone has a time limit of 30 minutes max except for google and Safari which have a 5 minute max time limit each. The only app that does not have a time limit on it is texting that shuts off after 9PM. My boyfriend has never done drugs or been a troublemaker. We’ve never sent nudes or anything. He has had these restrictions since he was 12 and got his first phone. I think it’s a little strict, I don’t want to tell them how to parent their child, that is not my issue, I just don’t like them look through our texts and listening in on our calls. It makes me and him very uncomfortable. I can’t be all lovey dovey on the phone with him because he’s afraid of his mother judging us. She will tell me and him her 2 cents on subjects that I text him about privately. I texted him “gd” and she got upset because its “the lord’s name in vain” It feels like I am texting his mother not him. He paid for his own phone and offered to pay for his own texting plan but they won’t allow him because he’s under their roof. He is also 16 so he can’t move out. I tried to calmly ask the mother why she checks all his texts in the first place and she threatened to take away his phone if I brought it up again. I can’t even get a explanation as to why she does this. He’s a really nice guy but I’m not sure if I can do this anymore, my friends are telling me it’s not worth it but he’s my best friend and it’s not his fault. What do I do?

Btw he also has a older brother who is 18 with the same restrictions, he can’t move out because he’s a full time student.
