I'll say something that won't make sense or be appreciated but I wish someone had said it to me when I was missing someone who didn't have time for me: Move on, put him in your rear view mirror and wait for someone who does want to be with you.
I know, you want only him around but time is valuable. Make the most of yours. Life can be good when you're with someone who appreciates and values you and wants to be with you.
And in the meantime learn to enjoy your own company and do things by yourself including movies or whatever you can manage. The most wonderful person on earth is worthless if they don't have time for you. When he does decide he has nothing better to do and contacts you, you will be too busy to see HIM!
I know all this was useless information because you only want him but at least you got some good advice, even though it probably won't help.
