I've been putting everything into this relationship for eight months and realized I've been doing it alone

Me and my girlfriend have been together for eight months. From the outside it probably looks fine. We don't fight much. We spend time together. Things are mostly good. But I've been noticing something for a while that I kept pushing down because I didn't want it to be true. I'm always the one who texts first. Always the one who makes the plans. Always the one who asks how she's doing, checks in when something is going on in her life, remembers the things she told me and follows up on them. I thought I was just being a good boyfriend. I didn't notice for a long time that it was only going one direction. Last month I decided to test it. Not in a manipulative way. I just stopped initiating for a week. No first texts. No suggesting plans. Just waiting to see what happened. She texted me twice in seven days. Both times to ask if I could give her a ride somewhere. I don't think she's a bad person. I don't think she did this on purpose. But I've been so focused on showing up for her that I never stopped to notice she wasn't really showing up for me. I started thinking about whether this was just how she was wired or whether she actually valued the relationship the same way I did. And whether those were even the same question. I realized that staying quiet wasn't protecting the relationship. It was just protecting me from a conversation I was scared to have. The longer I waited the more I was filling in the gaps with my own fears. I decided I'd rather know the truth than spend another few months giving everything to something that was only going one way. I'd been so focused on not wanting to seem needy that I'd never actually said anything. Once I saw that staying quiet wasn't protecting the relationship it was just delaying the inevitable, I decided to bring it up without making it an accusation. Just tell her honestly that I'd been feeling like I was carrying most of it and that I needed to know if she was as invested as I was. I wasn't going in expecting a specific answer. I just knew that almost convincing myself it wasn't worth bringing up and then not saying anything was the one outcome I'd actually regret.
