Take one thing at a time and get moving.. Keep your crush out of the picture and review your relation. See if it makes sense for you to continue in your relation or not. If you think there is no reason to break it up, give your energy and time to try to build the relation up. If needed move to another place where you can spend more time with your bf and work on your relation.

If you decide that you need to get out of the relation, work on it with your best freind. He would understand the situation and help you best on how to get out, and in the process you both can build a relation with each other.
