Tell your friend to tell her your busy Sunday.Dont mind giving excuses ,your busy and thats it.Tell him while he is talking to her to pass on your no on to her and to tell her to text you whenever.This way your throwing the ball on her court totally.If she wants to meet you she will make the effort.A date or relationship or whatever is 50 / 50.Let her make some effort for a change,you've made enough ,now its up to her.
lets see if she'll kick the ball,
Westside.
bu the way in case i forget.Dont go sitting around waiting aimlessly for her text.Might never come,dont forget to carry on living.
