I'd like yo know if we are compatible with each other. I am a dragon and he is a pig.

Hey, you two will be good. At the beginning, you both fall in love crazily. After your passion is gone, you both will take your relationship serious and consider building a family together.

For you, you shouldn't have to be very suspicious. He promised to see you and he should have come on the appointed date. You should take this opportunity to figure out what kind of person he is. If he didn't come and find many excuses, then I am afraid that he doesn't take your relationship serious. Then time to leave him.
