Grow some balls and quit ghosting
I get that it's easy to run away from situations you find yourself in. We live in a time where you could be talking to someone across the world one day and never speak to them again. It's very easy to dismiss regrets or anxiety with distractions. This is no excuse to treat people like they're disposable. If you have problems with confrontation, then you shouldnt have relationships (platonic or intimate). If you can't express your feelings or have difficult conversations with people in your life, you need help. I will admit that I struggle with confrontation as well, and I still manage to muster up the courage to speak when necessary. Running away from all your problems will leave you feeling considerably depressed on your deathbed. People lack integrity today, and it makes me question getting involved with anyone anymore. It seems like no one will be real cause they have no backbone and just want to be cordial. Ghosting and ignoring being the norm in society will advance our growing resentment for one another. Life is scary, people are scary, get over it and grow up.
(There are certain situations involving abuse that would excuse you ghosting someone, not just because you don't want to be with them anymore, that makes you shitty)
