I want kids but my man doesn't... Help

Valerie • Loving life just really waiting
I want kids have wanted kids all my life. I came from a family with brothers and sisters. So I wanted to have a big family. Well my boyfriend and I talked before we even started dating and he was all for it. He never told me he had a kid from a previous relationship. But he's not his biological kid he raised him cause the mother was a whore and slept around she says he's his but even he knows he's not everyone can see it he's of a different race. I have niece and nephews of the racial mixing he should be and he's not like them at all. Well sorry for going off topic.... Ok so like I talked about we talked now he's telling me he don't want kids and that maybe I should find someone else that wants kids but I don't want anyone else. I even told him that I would tie my tube and he says no I better not. I can always get them untied. I don't talk about with him no more cause we end up fighting about it. And his so called son is nothing but trouble he steals from my house he stole from my purse, dose drugs and lies. All I want is my own little bundle of joy with a little bit of me and my man In our own child. A child that has his blood running through their veins.
