Do/check all the above ^^^
Also is your saddle fit your horses properly? If it doesn't that also could be why it is slipping.
Riding a horse is not a gentle hobby, to be picked up and laid down like a game of solitaire. It is a grand passion. It seizes a person whole and, once it has done so, he will have to accept that his life will be radically changed.
