He didn’t really have a reason, he wasn’t doing much at home anyway so could have spared 2 short train rides to come to Gatwick… I half-jokingly implied we could meet halfway, to which he agreed immediately.
I asked him a few days before I left ‘are you gonna pick me up at the airport?’ and he said yes without any hesitation, however it didn’t come from him, and I find it rather strange not to even suggest that in the first place when your girlfriend is coming from another country to visit you..

He came to visit me and I picked him up from the airport without any second thought…

He definitely doesn’t have any Aspergers and he is a smart man, and socially apt in many different situations.

The fact that he purposely chose to come to our university city a few days after I arrive (knowing I had chosen that date to be there for his bday, but still coming afterwards) is a big fat slap in the face.
