My girlfriend has a habit of being forgetful about things. I've come to learn this early on in our relationship and it's been pretty obvious that she sometimes struggles remembering in different aspects such as doing tasks, remembering where she placed stuff, and even conversations and details. It's not too bad and is justified as they can be small, insignificant things but here's where I need advice on.
She forgets a lot of details about me/our relationship. She would often forget the details I tell her about myself, things we've done together, and even ones I've considered important for us. She'd say she'll do something for us, or something I've requested her to do, then would forget about it. I know it's not her fault, and she acknowledges that her memory is pretty bad, but I still can't help but feel hurt and disappointed.
An example of the things that I feel pretty hurt about is that I've given her a gift on the day we became official. It was a book I made, asking her to be my girlfriend. We've had instances, more than I can remember where I would ask her what the title of the book I gave her was and she could never remember it even when I would always tell her in the end. If I ask her in another time, she wouldn't be able to answer it again.
It's a petty thing, and it could also feel like I'm testing her, but I just kept hoping that maybe she could remember it from just how many times we've had that conversation. But every time I was left disappointed.
I don't want to blame her, and from some quick research on the internet said it could also be a symptom of ADHD or some other condition, but she isn't diagnosed so I have no way of telling. I don't want her to feel bad for it either, but I can't help but feel sad every time she forgets.
I know I might be unreasonable and unfair to her because maybe she just can't help but be forgetful at times, and that I'm expecting and asking for too much. I know it could just be overreaction in my part, and that this shouldn't be a big deal. I just need another perspective on how I should accept this and understand her better.
**TL;DR** : partner forgets a lot of details in our relationship even when we've talked about it and I've reminded her multiple times.
