Relationships

So I’m 17 and my boyfriend is almost 20. His best friends just got married like a month apart from each other and are both expecting kids soon. My boyfriend sat me down the other day and said how he wants to have kids and get married next year. I’m a senior in high school and work part time almost everyday and he has a amazing full time job. I just don’t know if it would be acceptable at my age or what I should do. I mean for the past year and a half I’ve know I wanted a future with him and I’ve really wanted kids I just don’t know if it would be acceptable or not?
