Married men only. If you are very attracted to a woman and are trying to connect with her...?

A married man and I are VERY attracted to each other and are trying to connect without seeming inappropriate to those around us which is very difficult. But on the rare occasion that we do speak on the phone about business when it is just the two of us around he always brings up his wife as it relates to the business at hand. Is he doing this out of guilt? Trying to let me know to stay away? Or do guys not think about it and I'm reading too much into it? He tries to keep me on the phone by talking about other things but we both get so flustered with each other I just get off the phone after we are talking about a schedule and he say's " I'll talk to my wife and get back to you" when he could have said "I'll check on it and get back to you"
