Does it make a difference if your spouse cheats only online, but never in person?

I’ve heard women say that affairs of the heart bother them more than sexual affairs where there are few feelings. In both cases, there is physical sexual contact in the real world.

Online relationships can be just as intense as real world relationships, as far as feelings are concerned. But there is no physical contact. Does that make a difference as far as you’re concerned? Does the fact that there were never any physical fluids exchanged make a difference?

What is that difference, if any? I mean in terms of feelings and fears and anger, not the obvious physical world difference.
