I invited her go out with me and my other friend and his girl and it basically is like a double date. I carefully worded the way I invited her so she knows she is going out with me, and not a group hangout. I am texting through instagram, when I asked her to go out with me she replied with,
"Yea sure we can do that"
then I said,
"Okay cool it will probably be next weekend"
to which she later replied with,
"Yes we could bring my cousin"
where can I go from here if I didn't want her cousin to be part of the education, because he would be a third wheel.
