Sure, if he and Cora had indeed had a child together, she may have been raised with love. But she still would have been used for the Dark Curse, left with a gaping void in her heart, and he was prepared to use his own child for that. In fact, he was planning on it. We don't know what were his plans after he changed the contract. Originally he wanted to use Cora's child to cast the Dark Curse, but he fell in love, changed the deal and maybe he was ready to abandon his ideas of casting the Curse. Maybe he wanted a new fresh start with Cora and their child. He finally had someone who loved him and there was a good possibility of making a new family. After Cora broke his heart he lost any hope of having someone who is able to love him and that's why he didn't believe in Bell's love for him.
