I've been with my partner nearly two years, we live together, and recently I'm finding it really frustrating that he just doesnt seem to have any interest is proper chats and discussions, beyond day-to-day talk. His response when I try to initiate conversation about the world/ideas tends to be 'what will be, will be' or, 'who knows' which is quite a conversation killer.
Is there any way this can change, or should I just accept this is who he is and try to get stimulating conversation from other people? I have mentioned to him a few times that I feel we dont chat enough but things dont really change
