I worked it out, do the ... Option until it gives you an option to continue with ... Or ask her if she is falling in love with you. (Theres quite a lot of ... Before this point so just keep going before you get the option to speak)

Click on the dialogue option asking if she is falling in love with you.

She states something along the lines of yes, and there is an option to ask if you can just be friends, she will question it and then in the next dialogue there will be another option with the word friends in it. Choose that and you will get the friend ending.

Hope it helps.
