I agree wit the poster who said that if you see providers while married, you just try to justify it with a spin. You can try to make excuses about not getting any after marriage or that you aren't in love or are staying together for the kids, but when you see other women behind her back and adopt an ignorance is bliss sort of rule, its still keeping secrets and spending money she doesn't know about.
I mean you did get married and do vows and sign some contracts saying you'll be with them for the rest of your life. I figure if the lady in question found out about the sp's she wouldn't be too happy about it. If she already knows, or adopts a sort of I don't wanna know, its a completely different matter.
