AM I THE DELUSIONAL ONE?

why do I feel like I am an add-on in my relationship with my husband? (a bit late) but I realized I might have a real narcissist in my hand. He constantly talks about himself and like to hear other people talk about him. if he is not interested, he won't even entertain the conversation because it is not about his feelings, his hobby or his job. I told him I am not happy, and he keeps bringing the times when he was not happy too. I told him yesterday I want to travel for my 30th birthday, and first thing he said is that I can't because I have to wait for his 30th birthday. is it so bad to think that I deserve better and want to leave him even if he provides a lot? is it bad to think our child will have a better life if we get separated? or am I just delusional and he is not a narcissist and I should be more patient?
