Is he trying to tell me something?

Mutual attraction with this guy, who is also a good friend. I feel like he might be sending me romantic signals but I'm not sure if that's true or if that's just my wishful thinking. Horary chart attached.

I'm not seeing him sending romantic signals to you. There is clearly potential mutual attraction in the synastry between you posted earlier. And we can see he/Saturn likes you/Moon, based on the favorable reception from Saturn to Moon. But he appears to be more concerned with himself than you at this time, since he is strongly in his dignity and his in his own/7th house.
