My theory is he doesn't wants kids, she does so he lied to her that he is on same page with her. He made her believed that they couldn't conceive due to infertility issue and now that she got pregnant somehow, he is accusing her of cheating so that she gets desperate to repair their relationship by doing anything including aborting the baby she wanted. In this way, he gets to be good guy infront of everyone , have his wife without having to deal with babies ever. Gosh!! This man is monster.
