Thank you.. to the both of you! I think I just needed someone's positivity. I'm becoming more comfortable with my decision. Sometimes the biggest battle, is myself. I don't like what I see.. but I'm changing it every day.
There's nothing wrong with you being a heavier rider, however, you need the right horse. This fine boned, long backed, delicately put together gelding ISN'T the right horse.
I have a 15.2 h TB gelding that I wouldn't hesitate to let you ride, because he's built like a tank, has good strong bone, and is conformationally very nice. All the things this horse in which you're interested doesn't have.
The horse who is best for you is out there, but it's not this one.
