Thanks for your thoughts guys. It's definitely been weighing on me and I'm leaning towards moving on. I had a talk with him last night and I'm still not totally convinced one way or the other, but I figure I'll look at things objectively for another month and see where we stand. I'd already been looking at putting an expiration date on things. I can be patient if I need to be, but I can't fly blind.
In better news, I've been looking at learning how to do pleasure driving, and managed to get several recommendations for people in my area to teach me or help me find somebody to teach me. The person closest to me has Friesians, but I'm still leaning towards minis for multiple reasons (cheaper to board & feed, for one). I have my next groundwork clinic coming up on the 9th, so I'll get more exposure to working with minis there too.
And is it SPRING yet? 28 degrees here this morning. Unacceptable!
