if you found ur partner had been chatting to women online/ msm lots of them and had a dating profile saying 'single/ looking' but said it was only to chat to women as he is lonely; sneaks off to chat to them at night ; and doesnt tell you he's doing it...would you feel betrayed or think oh well let him has his fun as long as he doesnt do anything....? where is the line? why do i feel threatened and betrayed?
