I am not here to cause you discord. I am just trying to make a few comments. I don't mean to be so hard on your BF. Only you know the whole situation so please excuse my comments if they sound harsh. I don't mean to be harsh at all.

The Schnauzer breed is high strung by nature, tend to be barky, very loyal, attentive, protective and many can have anxiety due to being away from their person. My schnauzer had separation anxiety when I was away. They tend to be right behind your every step and really dislike being far from those they love. You mentioned that you can train your dog to not like you as much. That is a huge farce. You can't take your dog's anxiety away by distancing yourself from the dog. That will make it much worse. What Shiloh wants is to feel more connected to you as you can't change your dog's love for you. They are much happier when they are close to their loved one.

I feel if you think that you can change your dog's behavior by making him not like you is most certainly going against nature and this will just cause more harm. Take this with a grain of salt but in my experience with this breed, you have a little soul who will worship the ground you walk on so please accept this.

Take care
