Don’t ghost.

Learn to work through problems, rather than running away from them. One day there will come a problem that you can’t run from, and if running is all you’ve ever known, you will not have the skills you need to make it through that situation.
You may think it’s healthy to ghost people you find “toxic,” but it’s really not. You’re not only taking the easy way out and depriving yourself of useful life lessons, but you’re also causing serious psychological harm to someone who is probably already suffering from that.
Quite often, the people we tend to think of as “toxic” are just hurting and need help. It’s likely that they’ve been abandoned numerous times throughout their lives because those they rely on for support just write them off as “toxic,” give up on them, and resort to ghosting, rather than seeing them as another human being with feelings and needs.
Yes, you have needs too. But you cannot simply destroy another person’s life to meet those needs. You need to learn how to voice those needs. 90% of the time when people get ghosted, it’s very sudden and they don’t know what they did wrong. So how can they know what your needs are if you’re too afraid to let them know? Why punish them for your own shortcomings? If you’re a selfish and cowardly enough person to punch a permanent hole in the life of someone who loves you, then maybe consider that you’re “toxic,” too. And if they still love you even after you’ve done this to them, maybe they’re not as toxic as you thought. Maybe you threw away a really precious thing that’s hard to come by called unconditional love. Maybe you could both find happiness if you didn’t shove it away out of selfish fear. How can you expect to receive what you, yourself can’t even give?
