I would just go about your normal life. I think he is giving you a number of mixed signals though, which isn't a good sign. I would talk to him a bit more. For all intents and purposes, if you are told: to go out and have fun, that you are no longer in a relationship, he acts distant, and that you won't be seeing him for a few months, I would only assume you shouldn't have to live by any rules whatsoever. It is less healthy to be quasi-involved with someone you don't see for months/are waiting for them to come back to you than it is to be upset about getting over someone and maybe exploring other options in the process. Who knows, if you try having fun you might find that this summer couldn't come soon enough or that you've found another great opportunity in the process. First step is fixing the whole you can't do this can't do that situation ASAP!

If he broke up with you then you're fair game.
