I just read your post. I love how you are thinking of almost everything. I hear the urgency in your words. I don't necessarily think the pup would be a bad choice for someone since he did stop the shivering when the man picked him up. Though I would say he is going to require a lot more TLC and time than an outgoing pup might. He is probably going to be a bit babified and probably will be a cryer. Possibly screaming at night or during the day. I honestly feel you will be a very responsible owner....but I'm not sure the timing is right for you at this time. I am afraid that it would be too much on a pup right now in a split home sort of situation. Sorry if that sounds corny. I am concerned that you are concerned about some of his time with your boyfriend. I am also concerned that you can't have him at your place. Do you feel like you could possibly find a place that allows pets and get a new puppy then? I hope I am sounding gentle, because that is how I am meaning this.
