Tinder boys

Last year I matched a boy on tinder we went on a few dates but then he blocked me off everything just out of the blue one day but there back in April he matched me on tinder again and added me on Snapchat again,had meet up a few time but we both agreed to be friends with benefits so have seen him lots of times this year but other day he text and ask if i was getting much sex and replied saying yes and he said he hadn’t done it from we did it and oh and he said we’re fuck buddies don’t matter then the night he said play our song and tag me in the snapchat, I’m so confused
