19 wanting a baby help!??

Heather
I'm 19 and my boyfriend is 43 he looks nothing his age but I'm really wanting a baby with him I Love him so much we have literally been through it all! We have talked about it but idk. Idk if I should start college and finish school or have a child. I can do both but he's not getting any younger lol. I'm also wanting to marry him within a year or two. (Wanting) he does have 1 daughter she's 15 I really don't like her she has said some rude things about me she's one of those who talk so much shut but can't talk it to your face. But I know I want a life with him regardless of her. I don't know what to do!
