Cancer woman & Aqua man, what do you think?

Me: cancer sun, gemini rising, gemini moon, cancer venus
Him: aqua sun, gemini rising, scorpio moon, capricorn venus

We were in a relationship 4-5 years ago, fell in love very quickly and very deeply... but due to immaturity, insecurities, we broke up.

We've recently gotten back in contact. I miss him and realise we can still talk forever about nonsense, I can be silly and he won't judge... I don't know how he feels about me, or if he misses me... but I'd like to tell him I think about him still. Bad idea?

I've dated others since him but I always compared them to him, I'm 99% sure hes not in a relationship right now
We may have just been catching up just as friends but who knows?! Do you think we are a good match or not?

Contact him and see whether the two of you have matured down the same path. No point analyzing until afterwards.
