Dating advice

I’ve been talking to this guy for around a month and after a couple dates I realized that he isn’t the person I would want to be with. I met him as he delivers to my job, so I would see him very briefly every day. However he got very attached very quick even though it was one month. He’s told me that he’s gotten played over by all his relationships, and me cutting this short would only reaffirm that belief. What should I do and how should I approach it? I would still have to see him regularly everyday even though it’s brief.
