I regret getting a puppy and I don't know what to do.

Well, I appreciate your honesty and pragmatism. You are not living a lie like most people do only to turn into mercenaries behind closed doors. You can only bite what you can afford to chew. Just surrender your puppy to your boyfriend. Affection is a requisite intangible for all pet keepers. But what about looking at the strengths and positive qualities of this dog? Always have a second opinion to every situation. It may turn out to be the dog you wanted.
