Emotionally Swayed

Evidence that imply an unnatural relationship, an emotional affair:

→Keep in contact through all means
→Stalk each other on social media
→Leave special entries for each other
→Buy gifts for each other
→Always claim that they are not close

All the above are done in secrecy and lies

Of Co's, with the above, you may not be able to prove your partner is having a affair. What can you do if your partner refuses to admit right?

Well technically speaking, it's not an affair. Just emotionally swayed, if you must define it, with 'justifiable' lies Co's he/she doesn't want you to be unhappy.

Still, lies and more lies. How much will you tolerate?

Choice is yours. If you can live with it, if you can believe that your partner won't do it again, then go ahead and forgive. Else, think carefully Co's such people will always think that what they are doing are  not considered affairs, and lies are always justifiable. So the chance of it happening again is very high.

Did I mention you will be portrayed as unreasonable and over sensitive? So if you can accept such terms in yourself, good.

Note: Culprits of such emotional affairs are usually the so-called nice people.
