I agree with what you said about maybe not being as sensitive to CeMar as we would be others. I myself though my reply was short was just trying to assure him that this could be normal and not a slight towards him. Though do to the state of his sex life he may be taking it as such,
The now lets take care of you statement. I guess tone fluction and apparent mood would indicate if she is seeing this as a chore or more a statement of now its your turn to have a O and just not conveying it well in her words.
The covering up and distance she is putting between her and CeMar after the fact to me is a definate sign of her withdrowing from him which leads me to believe there is a larger problem and the EC is not there in the bedroom for Mrs CeMar. I myself have been guilty of these same actions. The hardest part is CeMar does not open up about other aspects of his marriage so what can a person say to offer insight into the whys and whats and is it possible that this might make her feel like that.
