It can. But is reliability really the #1 attribute for people out there? Most people want a partner who excites them and who makes them happy. If they're unreliable then that can be a problem but usually a very desirable person has reliability in addition to everything else. When you're settling - you're usually settling for someone who is at least reliable but isn't very exciting.
After dating lots of people, one of the major factors in what made me decide to build a life with my wife was that I could count on her to be a reliable partner. That is soooo huge when choosing someone you are going to build a family with. It is way more important than any sort of animal sexual attraction.
Why not? After 12 years of marriage I told my wife that and it cleared the air. We both knew it but it remained unsaid for so long and had been having an adverse affect on the relationship.
Yes, it was a tough and emotional week. But things are better out in the open and we have started to rebuild the relationship on love, not lust.
She did ask if I was having affairs. But I honestly said that I'm finished with sex now, I've just no time or interest in playing the chasing games. There are more important things in life.
Almost everyone wants to be desirable.
