As you can guess from what we've already revealed, Aquarius and Gemini are both big kids at heart who love exciting activities, spontaneous adventures, and the ability to do whatever they want, whenever they want. Unfortunately, this is a terrible match for having actual kids. Neither party wants to step up as the primary caregiver and both can feel trapped by the responsibility involved in raising a family.
The other thing about this pair is that they both struggle to discuss their feelings. It seems strange for a couple who normally talk about everything, but for some reason, they can talk about anything besides what they're feeling inside. When emotions go unexpressed it's a recipe for a hurtful breakup, and we would suggest getting out of the way when things finally explode - it's going to be a wild fight.
