Am i being paranoid?

Earlier in the week, like Monday or Tuesday, my bf had me defrost some chicken for him to marinate and cook for the next day. He didnt end up cooking some of it until Friday. I was nervous about eating it and voiced how it might not be safe. Of course he got defensive because i "questioned him" and because his job is involves him in the kitchen. I dont know his exact job description, but i know they make him tastse food and he makes food in this high end restaurant/market. Hes not exactly a chef but he says he is and therefore knows what hes doing. That its perfectly safe to eat.
Its Sunday now and he just cooked the rest of the chicken and wants me to eat it. Im 10 weeks pregnant and the thought of eating chicken thats been marinating for a week is terrifying. But if i say anything, he'll get upset a nf say i dont trust him. Can anyone confirm or debunk my fear? Would you eat the chicken??
