Am I wrong??

I’ve been dating my boyfriend for about a month now, we’ve talked marriage and vague future plans but we both know it’s a long way off lol. He’s really close with his sister and today it somehow came up that he would consider his sister of equal importance with his wife someday, whereas I’ve known my whole life I want a husband who will put me first... am I being totally unreasonable or is this a normal thing to want and expect? I completely understand family is important and we haven’t been together all that long, I’m just curious what you married people think haha

Update: guys I’m not insane we’re not getting married after a month calm down 😂 when I said we talked marriage I meant we’ve discussed the idea, not like planned a proposal already! Jesus hahaha
