Have you also watched the movie? It's cannon and it happens after the anime. If you have, then I don't think there's anything else that talks about the Okabe in the Steins Gate world line, or further develops the story in that direction. Pretty much everyone agrees that this particular Okabe should just be left alone, and that his story is complete. And since Commitee of Antimatter was cancelled I don't think you can consider it canon, but if it gives you peace of mind, go ahead.

I'm not super knowledgeable but I hope that helped a bit.
