Welcome. My first reaction is I wouldn’t be making any deposits for catering right now. That doesn’t mean you won’t end up marrying him. It just means your fiancé seems less than enthusiastic right now. The Policy of Joint Agreement states to never do anything your spouse is not enthusiastic about. It easily incorporates fiancés and significant others.
Also, you two have been dating less than a year. Right around the 9-12 month mark, people reach a comfort level where they aren’t always on their best behavior, trying super hard to make a good impression. Hidden idiosyncrasies come to light. Annoy habits surface. Flaws become glaringly obvious. At this point, many relationships flounder. Others weather the storm and are stronger for it.
Pre-marriage counseling still sounds like a good idea. I know you’re hurt now and don’t feel like being vulnerable, however, this will be good practice for marriage. In marriage, spouses accidentally hurt each other, and both need to remain open and vulnerable in spite of the pain. Besides in counseling, you can see if your fiancé’s fear is temporary, or is deeper.
Finally, I’m not sure it was a good idea to say you wouldn’t talk to him until he could give you an answer. While I’m sure you had the best intentions, it sounds like you were punishing him, and there was the veiled threat that if he didn’t give you the answer you wanted, you wouldn’t be speaking to him again.
Radical Honesty is essential. For us to expect radical honesty, we have to create an environment in which it is safe for our mates to share information. Saying we won’t talk to them until they come to a decision isn’t really creating a safe environment for sharing information about the factors playing into that decision.
One of the hardest parts of relationships is waiting. Sometimes we have to wait on our mate to take action, make a decision, reframe an issue, etc. But, by waiting we give the gift of time and self-hood to our beloved.
