Beth is obsessed with chess, and it gets in the way of her relationships. Chess is her number one priority, and her only purpose in life for the most part, so she doesn’t see a need to form attachments with other people. This is, of course, a dangerous path for Beth, and I wonder as the episodes progress whether we will see Beth learn to prioritize chess less. But for now, given how Beth is already addicted to pills and has few friends, any future trauma might send her into a full-blown breakdown and I’m not sure if there will be anyone there to help her recover. On the flip side, since Beth is young and still gaining independence, it might be the best time for her to not have a romantic partner so that she can concentrate on learning to navigate life without her adopted mother.
