used and stupid

It sucks when you come to realize that your ex, who is now your friends with benefits will be nothing more than that. I guess im the stupid one for keep on agreeing to it. Even when i told him that i still have feelings for him and dont want to be with anyone else, nothing changed. We wont talk for weeks and then he will randomly ask me to come over. I just dont get how someone who used to say i love you to, doesnt want anything but sex from you now. I still feel heartbroken even though we broke up in february.
