I really feel for you, going through this. I think a lot of us can relate to having a partner not as committed as us, to keeping livestock, growing food etc. And sometimes this bubbles over when they resent the money, and probably attention lavished on our animals. I had my animals before meeting my husband - so he knew what my interests were. Now we have more animals and land, and he does nothing but grumble.
Well done on making your decision - it can't have beeen easy. I do hope you can manage to salvage something, and keep your smallholding going, even if its in a very small way.......its not fair to expect you to give everything up, surely?
Wishing you lots of luck.
