F buddy

So I though fwb were only supposed to mess around & not go on dates or anything lol . So I’ve been messing around with this guy for almost 2 years we talk everyday. We’re just messing around nothing serious I’ve asked him before what does he want he always says he doesn’t know. If he wouldn’t want anything else why would he asks me on dates I also spend the night over at his place sometimes. Have ya ever had a fb & ended up being more than just that?
