I [28F] feel indifferent towards my partner [29M]

How do you know if/when to walk away from a relationship if nothing is blatantly wrong?

The guy I’m dating is nice. When we first started talking, I felt emotionally invested, even getting upset when I was nervous things wouldn’t work out. We met on a dating app (he lied about his height and education level, which I called him out for and he said it was due to insecurity) and have been together less than a year.

More and more lately, I question if I’m attracted to him and find some of the things he does or says to be misaligned from my thoughts/beliefs. That said, we obviously don’t need to agree on everything and he does hear me out when I express concerns to him. And it’s not anything huge, we’re politically similar and not religious.

I used to be attracted to him, but lately I don’t really want him to touch me and hooking up feels more like an obligation. He sometimes gives me the ick, but I worry I’m just being judgmental. If I did end things, I’m sure it would seem like it came out of nowhere to him because nothing is inherently wrong/we don’t have significant conflicts.

I find myself enjoying my alone time more and being kind of relieved if he needs to cancel plans. But I’m also aware that I have an avoidant attachment style and don’t want to throw away something that’s healthy because I’m picky or selfish.

I’ve only been in this city for about a year and a half, so I think that establishing roots and community is also a point of anxiety for me. He and I don’t have similar hobbies, so even though he’s open to trying some of the things that I like, I find myself wishing we had just a little more in common (but I’ve never dated somebody I had much in common with so maybe I’d not actually like that, idk).

I feel silly posting, but prior to this relationship, I had been purposefully single and not even really dating for 2ish years after getting out of an unhealthy relationship. So, my relative lack of experience, long history of being able to do what I wanted when I wanted as a single person, and avoidant attachment style are leading me to question my feelings and what the right thing to do is.
