Let's talk about ghosting.

OMG, it’s just an “Irish goodbye.”

1st ghosting might be accidental:

2nd it mightn't be malicious:
I came home, via high school 1 day & was bedridden, for 2 years. I didn't even call my school, to drop out because of the immense mental exhaustion, my disability caused. So of course my friends didn't receive a call, via me either.

3rd Just like not everyone agrees that cheating's wrong or what constitutes cheating, the same applies to ghosting. I believe that the best thing to do's to discuss your beliefs, desires, expectations and/or deal breakers prior to dating someone. If they're within agreement with jointly creating these arrangements with you, then they've chosen to obligate themselves to accommodating them.

4th it's malicious intent.
