I don’t feel like I need to be with you, because of this baby. And my thing is, I don’t want to be with you, Luis, I’ve made my mind up already. I don’t want to be with you, so if I don’t want to be with you that means we have to co-parent and I don’t want to have to do that.” After suggesting adoption, he quickly turned down that option.
