The betta bug is merciless when it strikes. But that's okay, because I adore them! I talk to mine, too. In probably six months, I've gone from one to seven... Eight counting the original who passed. RIP Ares.
I definitely have a short attention span. When I was little, I was diagnosed with ADD. Then social anxiety, then borderline manic depression. Then we found an actual cause. I don't know if this has any merit for your betta bug- ADD correlation, mjoy, but I think it makes sense that people prone to attention deficit and other social disorders would turn to keeping multiple pets. It just makes sense in my brain.
I think, though, as long as the love for the pets is there, there's nothing wrong with having them.
