Confused about being in a relationship, 24M

I am dating a girl, let’s call her (S) but it’s long distance.

She tends to get upset/anxious over small things almost daily, and expects time, reassurance, and emotional effort. I have a hectic job and genuinely don’t have the bandwidth for that every day.

At the same time, I do miss having someone to just spend time with - go for walks, coffee, weekends, short trips. Something simple and in-person.

Now I’m confused:

Is this just a long-distance problem?

Or am I someone who wants companionship but not the daily emotional responsibility of a relationship?

From a third-person perspective, what would you expect if you were in her place?

And does this seem like a mismatch or something that can be worked through?

Looking for honest views.
