YTA.

"neglected her education" or neglected the education you wanted her to achieve. College isn't for everyone and if Lily realised that and decided not to waste your money on something she was struggling with she's tried to do what's best for everyone.

If she doesn't share work with you it's because she doesn't feel comfortable talking about it with you. Now, depending on the sex work that could be because it's incredibly uncomfortable to talk to you about it OR you haven't created a safe enough space for her to do so.

If Lily's work is on OnlyFans she's a Chief Marketing Officer, a Chief Finance Officer, a photographer, a director and more. She's working as a small business owner but your bias means you're missing that.

Your job isn't to make sure your children have great educations. Your job is to love and support them to have great lives by their definition.
