Hi everyone

just wondering if you guys think a marriage is doomed to fail if the female spouse is in love with another man? as long as that is the case the marriage will not grow anywhere and will just slowly fall apart, correct?

And if the female spouse is pregnant to the husband but is still in love with another man but decides to stay with the husband for the babys sake, that is not a good idea as that will not help the marriage get any better, correct?

Just need other opinions/advice on this and to see whether i am correct on the statements above
