Can you run out of (romantic) love?

Like, can you give so much and receive so little that your brain just shuts off whatever part is responsible for love?

Like I've been starting to think I'm aroace, the past few relationships I've been in, I have felt nothing. You know that sparkly, warm feeling you have when you see/hear/talk to/think of someone you love? Yeah, I haven't felt that feeling in a long time.

Or maybe I just haven't found the right person yet, idk
