What did he mean by what he said?

I asked him if we really online half dated he said no it was a setup by mistake, what did he mean by what he said? Another topic he asked me out to be his girlfriend on text then I said yes it lasted short period of time I ended it we did not go on dates, we weren’t seeing each other so it didn’t count as actually dating he still pretends that I’m his girlfriend causes me trouble
