> The obvious course of action when you are unsure about something is experimentation. However, a relationship isn’t an activity (like a job, hobby, or sport) to try and quit when you don’t like it.
Wrong wrong wrong wrong wrong. Naïve, self-defeating. every relationship is an experiment. and if you try it and don’t like it then you can quit any time.
> Also, if it doesn’t work out, I’m scared of leaving a broken heart in another person.
Yes. That’s the real problem, fear of the unknown.
Better to love and to lose, than to live and to never have found love.
