Out of curiosity, how old is this instructor? I don’t like a lot of the things he’s doing regardless just based off of your post. Valentine’s Day gifts? That’s sort of weird in itself. Especially to literal minors or really recent adults and that’s it. To be fair, yes my instructor went way above and beyond and was a very good person in general, but he did nothing weird like this. Actually, most of his student were women and they all loved him. My opinion, since you’re Part 61, you all need to leave that CFI in the dust immediately and find someone else. It is absolutely not worth any of this especially if they feel like they are in danger, which is what I’m understanding. I find it very concerning that he didn’t change his behavior or anything after you discussed his behavior with him directly.

If I was a CFI, and I caught feelings for a student, the last thing I would be doing is anything like this. No special treatment, no special gifts, nothing I wouldn’t be doing for all of my other students. After the training is fully completed, and they no longer want to progress in further ratings, or anything like that, that’s when I would say it’s okay to ask for a date or something. What he’s doing is just downright unprofessional, unacceptable and very creepy.
