Rowey11, gosh this is a hard one but I would just talk with him. Not about asking you out but letting him get to you know you so he will ask you out. Your other options to get him to ask you out is;
1. Ask him to a movie or a group event.
2. Ask him out (don't wait for him to ask you)
3. Whatever party you are going to, ask him to come or ask him and his friends to join your party
4. Talk to him, just talking is a good thing
5. Give him a sign that you want him to ask you out, like touch him on the shoulder, or kiss him on the cheeck (in private, you don't want to embarass him either in front of others)
I hope this is helpful, please let me know if you have questions. Remember, the best you can do is communicate to him. Many wishes for you
