I (26M) think I have lost interest in my girlfriend of a year (23F) and I don’t know how to proceed.

Here's the story, I met this girl at a pool party back in July of 2024 and I was enamored with her, she really didn't want anything to do with me and wanted to continue living her life as she was, but she'd always blow me off for a while, probably a good 6 months.

Fast forward to Feb 2025, she was talking to me nonstop out of nowhere and I was really happy about that. We continued talking and hanging out to the point where it took me 16 days to ask her to be my girlfriend. Our anniversary was 3/3/26.

Last week as I was watching tv, I had a very scary and real thought: "do I still love her" and instead of shutting that out, it stuck with me. I was having terrible anxiety and have sunk into a depression because I don't want to believe it's true based on morals and the guilt and shame because she's such a sweet soul, but I think it is true.

To clarify, she hasn't done anything wrong, in fact she's done everything right. She treats me well, focuses on the small things, makes me a priority, includes me in her plans for the future and wants to do life with me. She brought it up really early that she wants to get married and live with me, which I was super on board with for a very long time. She basically ticks all the boxes in what someone would want in a partner.

As time goes on I'm starting to lose interest in her, which is annoying to me because why would I not want someone as kind and caring as her? I started feeling this way about a month ago, at first I thought I was just overwhelmed because she's quite clingy, but I just don't want to be intimate with her and don't want to stay around at her house, and little things are starting to annoy me. It's hard to explain but it's like I'm turned off completely, and she hasn't done anything wrong to cause this.

We had a talk yesterday and maybe I just need space, maybe I'm not ready for commitment, I don't know what it is, but it's a scary feeling. I'm not getting younger and I don't want to get into this rhythm of wasting time with people who want a future with me, which I end up not wanting

TL;DR I think I’m losing interest in my relationship because I’ve been getting annoyed at the little things I used to love. I don’t want to break her heart.
