I have read the entire thread and am a little surprised that some usually fun, pleasant posters have turned a little ugly. I don't wish to cause further argument, as I don't believe it gets anyone, anywhere. I do however welcome debate. I think that the original post was mostly unoffensive, however ignorant. However, I can see why the automatic assumption that his wife was cheating would cause offence. I agree with the sentiment of Endued, we should be helpful and assume the best in people whenever we can. Some of you seemed to misread his original post. As I see it, he didn't mean any offence - so you are free to disagree with him, but don't rip him to shreds over a generally thoughtful sentiment. The original responses from the ladies also seemed perfectly acceptable to me, as they were responding to the one truly offensive remark in the imperfectly-worded post. I'm an idealist fool though, so what do I know? :smile: To answer the original question, no. Your wife is not cheating on you. Even if she were, the 'air build up' wouldn't be an indicator. I think you may have trust issues in your relationship if you doubt your wife's fidelity over such a thing. The 'air build up' can occur and it's not really anything to worry about. Some of the other answers have explained this in more detail.
