RE>>Would your answer change if you were also pregnant with his child at the same time the other woman was? Explain!
Has been known to happen. I know 'cousins' who are in fact brother and sister and the marriage survived. As did the other relationship. Up to and including blending 'cousin Lelia' into family events, eventually dropping the pretense of cousins. Mothers seem to tolerate each other. Father is quite proud of his off spring, all of them.. I think there are about five or six by various wives and relationships The attitude is what's done is done. Dad is a bit something else though, high liver, never employed for long, always on the verge of breaking into a 'great deal'. manages to sell cars, drive a tow truck on off hours and BS's his way through life..
but his wife and hs other lady are very intelligent, educated, beautiful, elegant women with great careers. Don't ask me, I just know them.
