I'm a 1990 horse he's a 1991 sheep, chances for us romantically this year and best ways to start it

I am a 1990 horse and he is a 1991 sheep. We liked each other last year but due to work and leaving university we didn't have a chance to start something romantically. There are still feelings there and I am trying to get bak in contact as we both share the same mutual friends and text sometimes. What's the best way to start this again? We had great chemistry and were really close friends. Do our zodiacs go together and how likely is it we can make something happen this year?
