The problem with having too much fun is that one person always wants to cut the party short. In this case, it's usually Leo who decides they'd like to make a proper go of things. Aquarians are known for being commitment-phobes, so obviously an imbalance in power occurs at this point. However, after a period of time, Aquarius usually submits, despite it not being their favorite idea.
You'd think Leo would be glad to finally have their lover on board. But what typically ends up happening is that they lose interest once they've tamed their Aquarius. It's a constant back and forth between these two, and frankly, it's only going to cause a lot of pain and heartache. Leo is a major hothead and Aquarius has a rebellious streak, so you can only imagine the types of arguments this pair get into when tensions are high.
