My grammatical instincts tell me that to start a sentence with, "The reason being..." yields something that in fact is not a complete sentence, even if what follows that phrase is an independent clause with a subject, verb and object. And yet, there have been many times when I have been tempted to use that exact construction.
The example I am thinking of goes like this: "I don't think I can choose one over the other. The reason being...
I suppose one solution would be to not start a new sentence but instead link the two into one sentence. "I don't think I can choose one over the other; the reason being..." The problem with this solution is that it makes for an overly-long, complicated sentence.
I'd like to know what the opinion of the experts is on my question.
Thank you.
