Confused & Lost 😢

I went on a date, it was amazing , he said I was the one lol and we were communicating everyday and right before our second date he told me that I was a good girl and he thought I was the "good time" girl but  I'm special and we can't see each other cause he sleeps with other women, and he doesn't wanna hurt me by lying cause I might  find out but he texts me still and tells me he misses me. What am I to do cause I really like him ?? FYI I cried so much cause we were speaking for a month before we went on our date. Am I an idiot?
