You're not automatically the "asshole" for telling your daughter that you expect her to move out when she turns 18. It really depends on the context, how you communicated it, and your reasons. Many parents expect their children to become independent around 18, which is legally adulthood in many places. However, the way you discuss this can matter a lot. If it was a respectful conversation setting clear expectations and reasons, that's reasonable parenting. On the other hand, if it was abrupt, harsh, or made your daughter feel unwelcome or unsupported, that could be more problematic. If you want, you can share more details about how you told her and your situation, and I can help give more specific feedback.
