I think it's good that you have the two of them to help keep each other company. You do want to continue to keep them in separate cages as lovebirds can be aggressive to other birds sometimes.
As for whether they will bond to you, that is very hard to predict. It's certainly very possible if you spend the time with them. As an example, I brought my first budgie home as a parent-raised, semi-tame baby when I already had my conure, and I had no means to quarantine then, so he saw her as soon as I brought him home. He was very shy and distant with me, while he tried to make friends with my conure right away. It took months to build a good bond with him. Sometimes I didn't think he would ever become very friendly. But after a few months, he started to come around and really enjoy spending time with me. Ultimately, he became a wonderful talker and just the sweetest, friendliest, most loving little bird imaginable. He was friends with my conure (they had an adorable annoying little brother/patient big sister type relationship), but absolutely loved people, too. He would always fly over if I called him, often I only needed to make eye contact with him for him to fly over.
Any way, it sounds like you are doing the right thing working with your lovebird.
If it is possible, you could try keeping them in separate rooms for another week or two to give you some extra bonding time with them individually (and it would act as a sort of quarantine, too). However, since they have met, they might try calling to each other in other rooms and become upset. They should be ok in the same room, too; you just need to spend plenty of time with them, sitting near them, talking to them, letting them explore when you can watch them, are all good ways to bond. It takes patience.
