Aquarius people dont Trust Gemini people??

I'm an Aquarius...and I realized that I can't trust Geminis even though I like them. I don't know...but I always think there's a gap between us. With other signs like Sagittarius, Cancer or even Scorpio or Capricorn, I can be more intimate with them. Sometimes my crushes and friends notice this difference...but I don't know what to do. Geminis like me more than I like them...I can't reciprocate in kind! I wanted to know if it's a personal problem...or if astrology has an explanation for this...
