Finally ending LDR, but still having doubts

My fiancé (30M) and I (29F) have been together for nine years and recently got engaged. I’ve been practicing law for almost two years, while my fiancé is an orthopedic surgery resident (PGY-3). We’ve been in a long-distance relationship for the past three years, but we still saw each other every other weekend.

Match results didn’t turn out as we had hoped, but I didn’t think long distance would be too difficult since we were only a 3.5-hour train ride apart. However, over the past year, my fiancé has struggled with it. He started questioning my love for him and constantly expressing how lonely he felt and how much he wanted me by his side /:

I just wanted one of us to have a stable income because, as we all know, residents don’t make much. We’re also saving up for our destination wedding next year, so financial stability has been a priority. But in the end, I decided to quit my corporate job, move in with him this summer, and take a new job that pays half my current salary.

I’m just not sure about this decision. On top of everything, we haven’t been intimate for the past three months—he’s just so exhausted (understandably).
