I think you give him some time. a few weeks maybe a month to see if he truly does take steps to improve his communication. maybe talk to him about actively trying to become better about communicating. maybe when you do ask him a question that he gives a short terse answer to you persist, reminding him that he is working on communicating better and being more open.
you are right openness and communication are essential to most healthy and happy relationships. so if he doesn't work on it and show some signs of improvement then maybe you move on. but I wouldn't drop the relationship right now without giving him a fair shot and improving

I will set a limit date of my "waiting him". If I see that the relationship might work, then I'll try it. But like I said, I won't wait him forever, I have my life and if eventually he can't be part of that life, then I'll move on.
