We recently had a puppy that died of parvo within a week of us bringing him home and I still grieve him (or the dog he had promise to become) often, and that was back in March. I imagine it would be even harder with a wonderful pet that you had a strong attachment too.
For your second question puppies are EXHAUSTING! I would say he will settle in, but some of it is going to be you settling in too. Dog personalities aren't dissimilar to people personalities in my mind. There are lots of them and they change over time. The thing will be are you willing to make the commitment to be flexible with those changes.
Side note: Try really hard not to compare this guy to your last dog. It's like comparing one person to the next. Love him for who he is, and I guarantee you will start developing an ease in your relationship over the next few weeks/month.
Good luck to you!
