<human>: I am friends with this girl I like and one of our mutual friends (lets call her Jess) is trying to set us up. Whenever Jess mentions about us two dating the girl always seems to say no (I also say no but that's just because I feel weird about people trying to set me up). I have only heard her say no once and the way she replied no seemed a little odd almost as if she didn't mean what she was saying (the other times Jess has messaged me about her replies on Facebook as she usually mentions it when we aren't together).

The girl and l aways seem to flirt whenever we are together but nothing that couldn't be played off as being friendly. Anyway, the girl and I were talking the other day and we decided to go on a 'date' and 'accidentally' snapchat some pictures of us together to Jess as a joke. She seemed really enthusiastic about it and to be honest I am too as I think it will be funny and it will be the first time we have actually met up alone.

I am really blind in being able to tell if anyone is interested or not but if she is wanting someone else to think we were a couple it is a good sign right? Or did I just ruin my chances by agreeing to go on this date as a joke?

Can you condense the text into a few key points?
<bot>: I am going on a fake date with a girl I like with the intention of 'accidentally' sending pics of us together to our friend who is trying to set us up. Did I ruin my chances?
