I'm just going to come out and say this.... parrots are not dogs and cats. You can't just breed them, have the parents raise the offspring then separate the parents and expect to have happy go lucky offspring and happy parents.
Whether or not you lose your bond with your bird if he were to pair up with a hen, he would not be a happy bird if you were to separate him from his mate.
If you want tame and friendly offspring, then you are going to need to hand raise the chicks. Usually, the chicks would be pulled at 2-3 weeks in age, but what if the parents don't know how to take care of the offspring? Day old chicks will require hand feeding every 2 hours around the clock. The formula that they eat should be around 105° F, give or take. Too hot, you cause crop burn. Too cold, the chick might freeze or have crop problems. Feed too much, you might overstretch the crop.
Besides hand feeding supplies, you'll also need a brooder, thermometer to check the temperature of the formula and another to check the temp of the brooder, possibly a hygrometer (if air within brooder is too dry, it could cause dehydration in the chick), a heat lamp, a heating pad, fresh supply of clean towels, etc....
And that's probably just the tip of the iceberg!
Sorry, but breeding should not be taken lightly! It's something you could lose sleep over, and if you aren't home 24/7 or you can't take chicks with you, then something could happen while you are away.
It's a nice thought, but chances are, you or your friend might end up without a bird.... because once they are bonded and you try to separate them so that they could be pets again, they might end up screaming for each other until reunited.
