Some people just need to deal with things on their own sometimes. If he is requesting time, give it to him. Just let him know that you are there for him. Don't assume that everyone handles things the exact same way that you would.
And after 2 years, I find this comment to be a little disturbing:
Me and my boyfriend have been going through a rough patch just lately and its mostly on his part.
His part? It takes two people to be in a relationship and it take two people to make a patch rough. Try to be a little more understanding of his needs and not think something is wrong with him because he isn't exactly like you.
