What would you do

If you saw that your fiancée or SO was liking half naked chicks models on Facebook? I saw my SO doing this and we got into a huge fight and I made him unlike all the pages that those were on. He barely uses Facebook anyway. In my opinion liking that stuff is emotionally cheating and you should only have yes for your SO. Has nothing to do with being insecure. It should not happen while in a relationship. It’s disrespectful to your partner.
