Welcome to our community! I'm sorry that you lost your first bird after only 10 years, but glad that you now have a new flock...
Can we ask what species of parrots your two birds are? And do you know their ages? Have you seen your two birds actually mating?
***As already mentioned above by a few members, the issue that you have is that you have two birds of the same species who have bonded very closely with one another, and now they want little to nothing to do with people..This is not at all uncommon and happens all the time. It's nothing that you did that was wrong, it's just their natural instincts...
***When you bring home a single parrot into your home, the people who live in that household become the bird's "flock", as they are flock animals, but typically the bird will bond extremely closely with only one person in the household. And there is no rhyme or reason why the bird chooses the person that they do to be "their person"...So when you originally brought home your first bird by itself, YOU bonded closely with him and you became "his person", and he loved to spend time with you, interact with you, etc. However, no matter how closely you bonded with your first bird, when you brought home the second bird of the same species and of the opposite gender of your first bird, unfortunately the two birds immediately bonded very closely with one another; and when a bird bonds closely to a person and then also bonds closely to a new bird living in the household, or in their "flock", unfortunately the bird typically always chooses their bond with another bird over their bond with a person. It's just how nature works, and it makes sense if you think about it, they would rather be closely bonded with another bird than with a human being. And especially one of the same parrot species and of the opposite sex, that's just how nature works...But unfortunately when this happens, there is little that you can do to regain that relationship you once had with your bird unless you separate your two birds, don't allow them to mate with one another, that's a given, and don't allow them to really interact much with each other at all, because as long as they are in-contact with each other at all, they are going to want to be with each other and not with you...
This is why most "breeding-pairs" of birds are sold as "breeding-pairs" rather than being sold as "pet" birds, because they are bonded to one-another and they want little to nothing to do with people...You can always try to spend a ton of one-on-one time with each individual bird by yourselves, away in a room with the door shut where the other bird is out of sight, and see if that might strengthen your bond with him again, but as Noodles already said, unless you totally separate the two birds, house them each in their own cages, and keep them from interacting with one another, he's probably not going to want much to do with you...And separating them but still keeping the female bird in the same house is probably just going to make him very frustrated, angry, and unwilling to want much to do with you.. I don't want to tell you to "re-home" the female bird if you want to have a close relationship with your male bird again, as it's not the female's fault at all that this happened and she deserves a good home too (and honestly often when you bring home a second bird, even of the opposites sex, they don't bond with one another at all, they often hate each other and can't be put together at all, you're birds just happened to really bond closely quickly!)
I wouldn't allow them to mate because you don't want to end-up with a bunch of baby parrots you might have to hand-feed every 2 hours (including overnight) if they happen to abandon them, not want to feed them, become violent with them, etc.), so I think you need to house them separately regardless of what you ultimately decide to do, otherwise you'll simply have a "breeding-pair" of birds. They should each be in their own cages, and this might allow you to spend some one-on-one time with your male to see if he's willing to want to be close with you as long as he's not housed with the female...But if he is still not wanting much to do with you, or if he becomes even more angry, frustrated, or even violent with you, then I'm not sure what to tell you to do, other than provide them with a great, loving home, and spend as much one-on-one time as you can with both birds.
