There is nothing wrong with sharer B, she's a lovely rider, but I'm not happy and I don't need her financial contribution as desperately as before we moved. Just haven't clicked with her. They are really really minor things. Anyway, how can I do it without hurting her feelings? I didn't think she would like the new place but it has worked its magic on her and she was saying how much she loves it, argh.
I'm on brink of letting sharer A have pony on full loan, don't need help with the horse and he's costing nothing to keep. For some irrational reason am terrified of having the conversation with her, am I being ridiculous? Might she feel rejected?
