Online affairs - How to heal from hurt?

A cheating partner is hurtful whether online and or off-line. As it is all about emotion and I suppose people in love online are feeling emotions as well. So the only thing one can do is allow time to heal wounds and or another love interest. However the trust factor now rises with everyone the person encounters as you truly never are rid of this ill feeling.

I have been cheated on by my ex-husband but it didn't hurt as much as give me an excuse to leave him but I don't understand how anyone could take an online affair seriously, to me there is no physical contact, sure the intention behind the affair would hurt and I suppose a bit of trust would be lost because of all the what ifs but trust is a hard thing to give in the first place and I would assume that it would be up to the individual person whether or not it was worth even trying to rebuild in the first place.
