Love Birds are pushy. When one of mine died I let him go back to the Cockatiel cage instead of his. He did not want to be alone. The problem was that he terrified the Cockatiels and had them all bundled together in one corner.
No matter what you decide on remember that they have big personalities in those little bodies and need just as much love and care as larger parrots. Most people do not think of the little ones as parrots. Because they are small they don't get the respect that would be given to a large parrot.
Mine were singing and chattering last evening. It was 9 and I could here them going strong. I forgot to turn off their light and did not close the cage properly. They were singing because they escaped and were flying around the room.
