Been in a long term relationship that has had its ups and downs.  Spouse has been very distant for years, regardless of my efforts to bring us back together and to have a happy marriage.  I have snooped in the past, and have always been caught doing so, or fessed up if I had.  Doing so, I have found some seriously horrible posts/discussions with persons of the opposite gender on facebook/reddit, but they were claimed to be a trap and put there intentionally for me to stumble upon if I snooped again (?).  Spouse still spends 80%+ of the day on the internet and it doesn't make me comfortable in any way, and has communicated to me that privacy is highly valued and that (my spouse) is a grown person and will do what he/she wants to do.  I haven't snooped in a long time and don't want to do it again as I understand it causes relationship strain.  Curiosity is what did it to me in the past.  Is snooping a common thing?  Is it normal for a person in a marriage to value privacy and be as stand-offish about it as my SO is being?
<bot>: Up/down relationship, snooped in past, saw some bogus stuff, bogus excuse was given for bogus stuff, recent high emphasis on privacy and spends all day on internet.  Snooping common?
