Carlie was the one, until they broke up after Spider-Island, they went on a truce but so far no news about her came up afterwards, yet I don't think they'll come back at the moment, maybe in the next couple of years

As for Superheroine Girl-friend, yes, Ms. Marvel and Mockingbirg are older than him but, how big can it be their age difference? I see Peter within 25-26 years while characters like Ms. Marvel, Mockingbirg, hell, even Felicia, rank around their 28-30s, so it could still happen.

Now, the less known character...that could be a more likely theory, maybe someone from a former series or a returning one could be a good choice for Pete
