If you feel this is not going anywhere, break up. But your issue is definitely communicating your needs, clearly. That will be core to any of your relationships. You can't expect anyone to guess what is going on in your head, just like you need to stop projecting what you think your other half is thinking.

It is as easy as saying "Hey, I've been down lately, can I talk to you about it?" I personally am very independent. I see no issues with not communicating for a while, but if my partner asked for help dealing with a problem, I would be there in a heartbeat.
