He's Evasive
If he is evasive about the future and doesn't talk or want to chat about getting married, he is not ready to take the plunge. These sometimes uncomfortable conversations are necessary to have if there is going to be a future. If talking about jobs, travel, family and any subject of that nature is taboo, he is not ready. You may be anxious to get married, but if you push it, things won't change. But with the right guy, they will have no problems planning for the future and it won't be like pulling teeth.
