There's this theraputic riding center near me called Little Bit Theraputic Riding Center. You can volunteer there or at places like it internationally to help riders and horses out, and be around them without riding!
Have a small farm for Horse Rehibilatation. And just so you know, if your not riding because of a fall, or someone got hurt, you should really get back on before you collect a fear of these gentle, calm animals animals together.
You could learn to be a farrier, massage therapist, chiropractor, saddle fitter, or a bunch of other things that would keep you around horses. You could also look into a job with a major retailer as a traveling sales rep and go to horse shows. If you don't want to ride, you could try driving, too. Just throwing out some ideas 😃
