If it is good for you then your hubby ought to see that and that should be reason enough for his blessings .. the same applies to her hubby . But at the same time doing it on the sly ......... well I am against that .. I do believe the truth no matter if it is agreed upon or not is always best .... I would rather fight for the right thing and lose because I i was honest then gain something through deception .. because that gain would be short lived ........... only my opinion though . i am not in your shoes
I wish you the best
