ISTP after all.

I met his aunts; his family, the people that were important to him. By chance I had opened the door and they were there, and they were happy to have met the girl in his life. He had a party in his (and his roommate's) house that night, and when we had the room to ourselves, we cuddled. It was as if all the sensuality in the world resided in the bed we lay on, and we were enveloped in it.

When I woke up, I was back in the world where our lives no longer intersect.

I cared deeply for him, and I know his affection for me was genuine, but at the same time I couldn't be with someone who found it so easy to isolate himself from the world, isolating himself from me, and who ran for the hills at the first hint of commitment.
