Respectfully, I disagree with some things said here. He clearly shows intent by deliberately going out to the yard when she is outside to make sure the dog is not with her. He shows intent by making sure that he walks the dog alone and without her, every single time. He shows intent by only allowing her now to touch the dog’s nose but nothing more. They talked for months about getting the dog together but he got the dog by himself. This has gone on for three years despite her obvious pain and pleas for change. He MAY be autistic, yet he is not diagnosed. Either way, it sure seems deliberate to me, his actions. And the main point is that it’s hurting the OP immensely, as it rightfully should. Now either she learns to accept it, something that is very hurtful and painful for her, or she makes a change and decides it’s unacceptable, regardless.
