While opposites attract it is sometimes difficult to keep them together. It can work but every relationship needs communication to survive. Don't just accept the fact that he isn't verbally communicating his affection. I've had that problem with my SO in the beginning. He had no idea what a conversation was. He thought I was too emotional, etc. but as time progressed, so did he. I had to keep reminding him that I am not psychic Silvia Brown and I could not read his mind. He is much better at communicating with me now.
Also, there's an age difference with you and your guy. Maybe, this plays apart? You know we gals mature faster!
