What does it mean if someone says "you lack substance"?

FattyFox
I went on a date with a guy who asked me my interests and then he slagged off everything that I said I liked, and said that I "lacked substance." I felt horrible and so stupid, and I never text him back after that! He didn't need to be so rude and keep going on about it and putting me down. But does his comment basically mean that I have no personality and that I'm boring? xo

It's interesting how a lot of people have said it meant I am shallow/have shallow interests, especially as I told him how much I *love* my job working for a homeless charity and on he side am volunteering else where supporting people with learning disabilities and mental health needs? i guess it probably is boring that I have a passion for that but he didn't need to be so rude. He didn't stop talking about himself and I would never dream of saying anything like that to anyone :(
