There is a difference between bending over and showing a young prospect some perspective. We don’t know what the club is telling him, how the club is planning with him and what his relationship with the coaching staff is like. Those things are very difficult to judge.
Maybe he just really doesn’t see any real perspective at your club. If that’s the case, he’d be right to move on to a club where he can play. Dortmund would be a great address for him, or at least used to be until they got rid of Tuchel.
If he chooses a club like Dortmund, it would indicate a good attitude to me. The willingness to go to a smaller club for playing time is usually a good sign from a young player.
