Is it right to evolve a friendship with the opposite sex into a "close" one when married? To the point of chatting with him/her first thing when you wake you up in the morning and the last thing you do at night when you don't even do it with your spouse? I call that cheating. What do you think?

What if both parties would do the same? As they wake up, first thing in the morning and before sleeping at night they would prefer greeting someone else on the phone first instead his wife or his husband? That only means someone is too invested about your friendship with someone else rather than refueling the fire with your better half. My father once had a friend from childhood. And my father used to text her constantly. Little did we know a friendship evolved into something deeper than friendship. Because he's too invested texting someone else than talking to his wife. I knew this but l kept quiet about it. As for me, boredom in marriage is never an excuse to cheat a partner. Or texting someone else with sweet nothings and with a smile.
