I have a friend with benefits that I hangout with 3-4 times a week. I only met her last month and we've been having lots of fun since. I find her very attractive and love spending time with her. Thing is, we'll fool around one day, then the next day when I don't get to see her, I miss her and feel kind of heartbroken and cant get her out of my head. The thought of her messing with other guys (which I think she is) bothers me. I try not to text her or call her too much because I don't wanna come off as needy. How can I stop obsessing over her?
