[Yeah there's that possibility, but Josak isn't going to tell Wolfram that when he's so worked up.]
You'll probably never stop completely loving him, but it'll get easier. And even one day you'll probably find someone else and all of this won't mean anything to you anymore.
[But he's also quick to reach out and try to keep Wolfram from going anywhere.]
If you feel that strongly about it, then sure, you should tell him! But maybe tell me first. That way you'll know exactly what to say when you see him and won't get caught on any of the little details.
