I can't do this

Percy still can't leave me alone, although he seems strong enough not to see me after work. He keeps sending flirtatious texts and he has this cute smile which would make anyone's heart melt. I need to let go, because he is taking me for granted and he can't make up his mind. One minute he says he is jealous if I go on dates, the next minute he says we need to text less. He can do whatever he wants, while I can't do anything. It really affects my mood. I know I don't wanna lose him as a friend too, but I can't go on like this. It's just too hard.
