Hi guys, thanks for all your support and advice. I decided to phone my husband last night and invited him round. There were so many questions i wanted answered. He explained to me that he had no feelings for this woman before the night it happened. The flirted all evening and it ended up with her coming back to our house. He admitted last night that she did in fact sleep with him in our bed, i think thats been the hardest thing to take so far. He said it only happened the once. As for the STD, he's been checked and said its all clear. I dont see how i can have anything then?
