The first person I had sex with it started out as just fuck buddies, but I quickly developed feelings for him and it immediatly fell appart from there. When I told him he began lying to me about how he got some chick pregnet and how he was engaged and so on so forth, all of which I learned from his brother is bullshit. This happened while working at a Boy Scout camp during the summer, admittidly I fell for him and I still would do anything for him, but I haven't seen him since camp due to the fact he lives a few hours away and the few times I called him he lies to me more. From my own personal experiances I think fuck buddy relationships aren't good because they are self destructive.
