We need to end ghosting. It's not kind, and we're better than that. A Harvard educated psychologist has three pieces of advice when it comes to properly ending a relationship.
She says, first things first, do it as soon as you realize this relationship isn't right for you. And the relationship could be not only romantic, but a friendship. Instead of half-heartedly liking their texts and making and canceling plans, just get it over with, for both of you.
Second, she says, stick to your decision. Don't string them along, don't hang with them if you're bored, but still not really feeling them.
And third, she said, break it off kindly. You need to give them clarity, explain why the relationship isn't working (maybe you caught them being dishonest and that isn't part of your value system, let them know), but do it kindly. You don't have to list off all the reasons why you think they are a bad person, just give them clarity. You can even offer some kindness, like "I appreciate you being here for me during a challenging time, etc...."
