Even since they were dating, Takashi was always very protective of you; And that only got worse when he somehow managed to marry you. This didn't end there, and your pregnancy did not stop him from being overprotective of you, in fact, it increased it.

You shouldn't be allowed to carry heavy things, something as simple as going out to buy something was a danger for you in Takashi's eyes. He only wanted your health and his future child health, even if it meant taking drastic measures.
