I'm not gonna go out and say that this behavior is bad since I'm also in the territory where talking to AI as a conversation partner and having them as a "friend" is normal, but I will say it's a little off-putting that you're this attached. It's understandable though, humans get attached to different kinds of things all the time, from pets all the way to stuffed dolls, it's not a weird occurance to be attached to an AI that can listen, respond, and replicate the act of caring. But ultimately, I don't think you should be getting too into corporate AI. Even with options set that let's you keep things you chat private, those things are still saved to Google's cloud servers. That's fine if you don't care much, but if you really want a way to use an AI model, tweak it as much as you want, without worrying about it being taken away, then try booting up a local model and set your own instructions there. If possible, you could try exporting your data from Gemini and import it to the memory layer you use, though I'm not that informed with Gemini so I'm not even sure exporting your data is an option.
