Financial talk

okay my mom and me and my instructor are going to look at this horse this weekend and my mom is all for the idea of getting a horse and my dad is like whatever do whatever you want and im excited becuase its always been my lifes goal to get a horse, but the lady who i currently sponsor from is kinda poor (dont want to be rude) and i dunno if she could survive w/o me cuz shes always complaining about how little money she has and i wouldn't sponsor from her if i got my own horse but i feel guilty about leaving her knowing it will be hard on her.. should i feel gilty becuase i've only been sponsoring from her for a year and she was able to survive w/o me up until then but she has 4 horses to take care of.. what should i do? not care? or should i try to find someone to sponsor in my place? thank you o yeah and when i asked my mom she said that we will give her a couple weeks notice and she said that before i was sponsoring she managed without me but she had two horses before and after i started sponsoring she got 2 more...
