@tyreesejack,
Like Jespah, I was going to suggest that the problem between you and your wife might have something to do with your fiancee. I'm going to guess they are one in the same.
If she is your wife and you have drifted apart, maybe it is because you no longer date but have settled in to a monotonous existence. Maybe before seeing a counselor, try to get back to doing what you did when you first met. Start going on dates together. They don't have to be expensive dates, just something to get you out of the house and doing something different. See if it helps. I'm sure it won't hurt any.
