Have an affair!!! But with ur spouse!! Spice things up a bit! If u wanna have an emotional bond with someone, who better than the one you love? Role-Play!!! But to answer your question yes it is! Thats y you do it with each other rather than someone else.
I say it's worse. Having meaningless sex is not as bad as bonding emotionally with someone. I could easier forgive something that meant nothing then my partner being emotionally connected with someone.
If your husband is not satisfying you emotionally and does not make an effort to do so and you have talked to him about it; then carry on with your affair. I must warn you; you will end up leaving him, but life is to short to be miserable.
Tough question. To me it's more the time and effort spent on the affair and how much it detracts from the primary relationship. But in the case of an emotional affair, that is very hard to quantify, which is why a physical affair always seems worse.
This has become much more prevalent since the massive development of the Internet. Psychologists studying this phenomena have almost universally concluded that it is the absence of what is said or seen in an Internet affair that allows the affair to grow so powerfully and so quickly. The Internet lover is perfect - the real life partner has human flaws - the fantasy diminishes the reality of the real life partner. A great many relationships and marriages break up over Internet affairs - only to discover - that when the Internet lover becomes actualized as a real person - the intense passion quickly dissipates.
