I really like this guy, and we know of each other, we were on the same sports team. But we don't really know much about each other we've only had small conversations. Is it okay to ask him out to get food/dessert?
Yep. He might say no or he's already dating someone or only sees you as a friend, but then you know not to waste your time with him and you can move on to the next :) I asked a guy out for a drink over fb lol and he told me he would have loved to but he is already seeing someone and we can meet just as friends. But i never bothered to ask again after that ;) haha so yeah, it's okay. Nothing wrong with it :)
