Confession ?

Solo I been with my boo for 3 years and he's always pressuring me and saying he want to have a baby . But I'm like no not ready. But in my heart I've always wanted a kid by him. So he's think I don't want kids but I do and for some reason I don't wanna tell him that I do want kids .. (He has two kids already) I guess I just don't wanna get hurt. I'm happy about starting a family but I want be his first ya know ? Any thoughts opinions ? I'm open thanks guys
