Romantic love isn't the only love of value. Love can be found in the most obscure ways you can think of, and sometimes it just comes in a form that is "I love you quite a lot platonically. I would like to spend the rest of my life with you.".

The issue with getting professional help when it comes to romantic attraction not being felt, psychologist, therapist, the like, are largely under-educated on these topics. The last time I told a doctor I was asexual, for example, they ran a load of blood work and scans only to find nothing was wrong with my hormones and I simply don't fancy sleeping with anyone. I can see the same thing happening when bringing up levels of romantic attraction.

They don't see it as a thing that happens, but rather something that needs to be fixed or corrected. Your best bet is speaking to people who are aromantic and self education, I think.
