But they're all behind the line. If we want to pass a clearly worded ordinance about every allowed and disallowed behavior in society then this is the game we are playing. It's not defending the guy, it's pointing out that if you want to live under clear laws, you can't just blur up the lines when it suits you.

Is the dude a scumbag? Probably. But I've lived long enough to see things go from legal but totally not OK, to illegal as it should be, to let's make everything illegal because someone else doesn't like it, and I fully expect one day that someone's going to try to say you can't fuck someone more than 3 years your junior no matter how old they are.

What this dude did is absolutely not socially acceptable, but what is socially acceptable is just fashion. Was it immoral? I don't know, did he lie to her about what their deal was together? It was most certainly not illegal, and nobody was coerced.

After her last day of school, before her last day of exams. Sounds like a position of trust to me... Did she even have her final marks in his class while they were texting each other?

Must've been mistaken about exactly how long he needed to wait.
