Am I engaged to a Narcissist?🤔

So tonight my Fiancé asked me how long I was taking my leave from work to care for our child, I’m taking my max leave of 6 weeks, my Job doesn’t do paid leave which I cannot help.. he’s getting paid for two weeks of his leave. He literally made me feel like it’s my fault.. our living situation isn’t idea, we pay $965 a month for our apartment which is ridiculous, I know but I had moved into this apartment way before I got with him and it was a last minute choice because I had nowhere else to go at that point in time so I moved into this apartment with very little and built my way up and worked my ass off for everything that I have today! $965 is NOT hard to save up I’ve done this by myself I’ve paid rent by myself and all my bills by myself before so I don’t see how hard it could be for him to save his money for once in his life to support his growing family!! I understand he’s stressing out about how we’re going to afford everything but saving money is so EASY!! I’ve been saving money since I started working and it’s why I always have money in my pockets and I’m never broke! He gets paid and his whole paycheck is GONE by the next day right after getting paid! I have not even touched my tax return money at all because I’m saving it for US when our child is born!! So I just don’t get it, I feel like everything is my fault and he’s just being a total narcissist about everything!
