Do I wait around for him?

So my boyfriend after a year broke up with me because he said "he couldn't give me what I deserve". He wasn't someone who put in a lot of effort and occasionally I would bring it up and compromise with him to meet both our needs. He really grounded me and helped me be a better person. I'm still not over him and he goes away on deployment soon, and a lot can change in 6 months. There's a possibility he may want to see where we go when he gets back but there's so much uncertainty. Do I accept that we aren't together and move on? Or do I just look after myself until he gets back and hope that we can be together again?
