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?

Nope, don’t think it’s right at all! Close female friends he had before marriage is fine, I’m even ok with them going out 1-on-1 to eat or drink. After marriage, there’s no reason why he should get close to another lady. Not to mention to such “closeness” somemore. I probably wouldn’t call it cheating, but I would make sure my Husband knows I’m really uncomfortable about this n ask him to stop.
