"Is your relationship good?" I'm going to say yes, based on a conversation she had with my wife the other day, where she asked "what's Pornhub?" She clearly felt comfortable to ask, rather than just looking it up without our knowledge.
I admit, I'm a little hypocritical, because I've purged my socials. Can't stand them, and I've discovered my life is *far* less anxiety-driven by removing them. I've even gone so far as to stay away from message boards; this is the only message board I participate in.
At the same time, I started getting online in 1982, when I was 10 years old. A 300-baud modem and a Commodore 64, and local message boards. There are still people in my local area that I know from that time. I'm in IT, including a field that's somewhat security based, so I'm always on top of security risks, mindful of issues related to being online.
Does she "need" social media? To a degree, no. Although it is a very useful way for her to stay in contact with her friends during these times.
I've spent hours discussing social media with my therapist; both regarding myself and my daughter. And one thing that came out of that conversation was "if she doesn't have her own access, she's going to grab her friends phones and access it that way." End of the day, by allowing her her own access, I can monitor what's going on.
We do have a great relationship, and we talk everyday about pretty heavy stuff sometimes. Part of the rules of having a phone and socials is that we are subscribed to her accounts, and that we have access to her phone, her texts, and her DMs. What's nice is that there's a level of trust, so although we can ask for her phone at any time, she also doesn't feel like we're standing over her shoulder (her words). We give her latitude and trust, and she doesn't abuse it (and trust me, I know how to get into whatever I need to get into).
Bottom line, even if I didn't allow her to get into social media, she'd still be with her friends, she'd still be exposed to these issues like politics, rioting, sex. At least this way, we know what's going on, and we can have open lines of communication. She's forming her own opinions, and challenges us on our, and I think that open discussion is ultimately a good thing.
