If you're that emotionally invested that early on, you may need to do some self-reflection. The early stage of dating someone is not supposed to be a serious-committed-relationship type of vibe. You really are just hanging out and getting to know whether you would like to spend more time with the other person. If you're so invested at that stage that ghosting is considered taxing to you, sit with your own priorities for a while and determine whether you're going into dating with a healthy mindset.

And you don't have to be ruthless to know that your time would be better spent elsewhere. Take the sunk-cost on the chin and move on.
