Should I stay or I should I go?

Hello,First thing sorry to hear about the horse you were riding.That's great you learned a lot from him i bet he learned a lot from you also.Spending $600.00 a month on a horse that isn't yours is crazy! If i were in your shoes i would buy my own horse.There are a lot of horses out there to chose from that need good homes and good people. I wish you luck in what ever decision you make. Happy trails
