Seven years ago, a "study" found that people who get incredibly close to death, meet their soulmate in their minds. People described them as an angel in the darkness, a light at the end of the tunnel. The idea alone made Tony want to hurl. It's stupid. Bullshit. Soulmates aren't real. Sure, Tony zapped himself every now and then. Occupational hazard. But as of yet, he hasn't come close enough to death to object the study with facts. And though he is a curious man by nature, he's not /that/ curious. His "soulmate" will show up on their own time. And if they don't? They don't. Whatever. Tony can tinker all he likes. He's content in his lab. Even if it's a little quiet sometimes... - Or: Every time Tony nearly dies in the MCU canon, he sees and talks with Peter (who ages appropriately - aka during Iron Man 1, Peter is 6 years old, etc etc etc).
