enemy's to lovers

I'm so confused about how everyone think tony and peter had a father and son  relationship
Like tony was mostly use peter
Like he didn't had  enough  people on  his team so he call peter and he blackmailed him to join him or he tell his a aunt about being superhero and and sure he made a suit for him but he takes that away and peter go after the vilian with his old suit and was under a bull and and then ignore him when he was saving his stuff like I think that kind was toxic relationship between them and didn't even tell peter why they were fighting against team cap like are you guys cool with that? I just don't understand stark fans
