Hi!
I am very sorry for your loss!
You can never love the same again because every bond is unique. The good news is that you can love again many times, but it will be different each time, as each relationship is unique. Usually a bond following the death of a much beloved pet it is more of slow 'creeper upper'. Don't expect the same deep bond, and don't aim for it. Be open and you will be surprised as you will discover new aspects and learn new things. But yes, you may come across another special piggy sooner or later that gets equally under your skin. But never try to get the same again - in that respect you'll inevitably fail.
In order to avoid any direct comparisons and unrealistic expectations, I would recommend to go in a very different direction with your next piggies. Look for a pair of sows, ideally a bonded rescue pair you can adopt from a rescue. That gives you a different gender and completely different social dynamics - and it won't take anything away from Archie. By going good standard rescue (if that is possible for you), you can neatly avoid the usual pitfalls that await the unwary and also do something good by giving some unwanted or neglect breeding piggies a chance at happy forever after.

After the death of my Minx 11 years ago, who is still my most special piggy, I eventually started a group adventure, which has been in its own way every bit as wonderful - I wouldn't want to miss that either! You can't compare the one with the other but they have both been very enriching. I have since met some special personalities that I feel blessed to have had in my life, each of them unique and none taking anything away from the others.
Give yourself time and look for a new start when you are ready or allow piggies to find you if they are meant to be.
