Hi gemini1689,
I'm a cancer female and I've been with my aqua for 3 months now. For sure, it's not easy sometimes, but so worth it. The only piece of advice I would give someone dating an aqua is to leave them some space. It's ok to have emotions, but with an aqua, you have to be careful. Emotional outbursts are not really their cup of coffee. Learning to leave him space was really hard for me to learn the first month, but now, I actually love it. If you want it to work, don't get clingy or he might run away like hell from you. Plus, it shows emotional maturity and safety to be able to have your own life when the other is not around. You don't want to show the image of a desperate girl who's crying her eyes out when her BF is busy for a few days. I also found out that aquas need to think a lot. He might be thinking things over, and it's not necessarily negative. So, please, relax. Do you while he is in his cave and hopefully, things will get better soon.
Good luck.
S.
