We have been together together for 7 years and had a great first 1-2 years. But then she let herself go in many ways. Not taking take of her physically, quitting her studies and she essentially has been staying at home most of the time, being unemployed and playing videogames. We still remained pretty close throughout but it certainly felt that my needs were neglected and the situation didn't change much as I hoped to.
So about 2 months I told her that I'm unhappy and we decided to try and work out the issues – and since then things are actually improving. She takes care of herself more, is actively looking for a way out unemployment and also plans things with me more often. At the same time I don't feel as motivated to work it out. I feel hesitant when doing things with her, often thinking I'd rather do something with friends and feeling emotionally absent, especially during sexual situations/kissing. It's objectively going better and it looks like the problem will improve even more but I feel like I checked out emotionally and can't get back to feeling in love. I feel like I can't tell her that openly without it leading to a breakup and I don't feel ready for that either. (We live together and have a cat)
Is there any hope it will change or should I let it go?
TLDR: GF tries to save relationship but too many years of unhappy memories are weighing down her efforts
