Why is it that every time my friends with benefits and I hook up. He then later on then disappears or get ghost and I don't hear from him for a while. Like I totally understand that he done got what he wanted and all. And I do get that he is only just a friend and we are hooking up and it's just sex. But why is it that he talks to me for a while then and there and tells me how good are sex is and how w** I got and so on. And even the next day we can have different conversations about other stuff other then sex. Then as the next day I notice it slowly starts to pull away, and are conversations become short to the point where I don't hear from him anymore. But then weeks or maybe days later or sometimes months I may hear from him or I end up sending him a massages on facebook or a text. So I don't know he hasn't said anything about are sex being bad. And I'm not sure if he is dating someone else. And I do understand that there are rules with friends with benefits. But he does hit me up even after sex or the next day. But then starts to pull away. So am I doing something wrong or is it him?
