Yes, lovebirds must be in a pair. My dad and stepmom have had them for years, including pairs they hand-raised. I think they are great! They are very friendly and will "talk" with you, tilting their head back and forth like they are listening to what you say :) Since you have had birds, you know all about the mess and upkeep.
They have had canaries and various finches too, but the lovebirds always showed the most personality, in my opinion.
