Same advice really. Just tell her you arent after a relationship. I had this last month. Was seeing this girl two weekends in a row and then 1 sunday night, I got a text saying Im really fond of you and want to know how you feel about me...I knew where she was going with the question and I had to tell her that I wasnt looking for anything serious and it was up to her whether she could accept that and would still see me again. And I got all this "oh im so hurt, you should be leading me on, you using me for sex"...! But she got over it and never heard from her since...! I should have made it clear from the very beginning but I never thought she would fall for me...! Hence all her accusations!!

Honesty the best policy I guess! Good luck dood!
