Just remember - the people helping here, or causing more panic in your heart in some cases - don't know the true situation.
Talk to your husband.
Personally, in the very unlikely event that I was having an affair, there is no way that my gf based 7000 miles away would have the remotest idea of it. What would I gain from letting her know? And, if I was having an affair, why would I spend time and effort and money in getting a wife over from the Phils?
Why not tell him you are having some male colleagues or old school friends around to dinner? If he is trying to make you jealous, show how much it hurts.
