Hi!
I (and several other members) wrote about the various paths a bit in earlier posts. As
Pr0GamerJohnny jokingly mentioned, you went fully on the darker voyeur route!
If you take the snoop skill at gamestart, you have many options pathwise, but you also have to be very precise which decision you make. One big thing to remember is that use of snoop is something of a parallel universe and mostly linked towards NTR as being a big show of general distrust! Snoop is a parallel development inso far, that scenes watched with it are far more severe and hard than those you do not snoop watch. For example, if you let your wife stay at the Xmas party and tell her to relax, but DO NOT snoop (choosing "Nevermind"), the event will happen, but it will be far more tame, partly even innocent, than if you watch!
You can see this that your wife does NOT gain the "drug haze" trait, neither does she lose love points nor gains Jamal points.
There are only one,two snoop scenes which can be positive, all others are geared towards NTR. In addition, some snoop scenes negate other events from happening, costing crucial opportunities. For instance, constant use of snoop will lead to your wife gaining several undesired traits while at the same time you will have no chance gaining some important trairs for the romance and positive sharing paths.
So you have to be strategic in your use of snoop, using it rarely and only for a scene or two you really want to see.
If you want a path with "just a bit NTR"(even if I would not use that term in this case), you yhould go towards the fun sharing path! This one starts to get hot with other persons just now (public version 0.24), but it is far from the dark paths with a couple in love and finding out sharing together.
