OK.......flat out honest opinion.... *zips up flame suit*
1) you may have paid too much for Denny from the get go, I don't think that's a secret but he made you happy so that's not really the point, my point is that you may not get all your money back out of him if/when you decide to sell him.
To me that's a calculated loss....you may or may not have known from the get go. It happens when we want something really really bad... like my hubby's saddle that he paid too much for, he'll never get all his money back...oh well, it made him happy.
2) if you and your dad want to work something out to purchase the horse of your dreams.......then do it! It's not OUR position to tell you what's right and wrong. Why would you be being selfish to sell the horse that injures himself on air that you have been 100% dedicated to??? You haven't short changed Denny in ANY way. You have simply changed your focus. Nothing wrong with that.
3) if you think your being selfish because daddy's helping you....DON'T. It's none of our business how you acquire your horse. Furthermore, your dad sounds like a smart cookie, buying the dream horse while the market is in the crapper is a SMART move!!! (Don't forget the market tanked in the 80's too and came back)
4) life is about being happy. You did fantastic things with Maia, you have resurrected a skinny, ottb, and mended his injuries with the best care. Now you have a decision to make...this is all about YOUR dreams and what YOU want from YOUR horse...Do you want to train, do you want to ride, do you want to show, what's going to be the best horse for your dreams????
Sure every horse nut dreams of their own personal black beauty waiting there to ride you into adventure and glory...but YOU have to choose what mount you will be taking.
Am I even making sense???
I'm just saying, if you want it go for it. BUT, you have to consider whether or not a Frisian will be able to keep up with your ambition.
Good Luck Allie!!! You are a smart gal...you'll do the right thing for you!!!
