>>108081416A lot of May’s bravado is clearly just her overcompensating for her own insecurities. She’s demonstrated a couple of times now that she very much cares about what her close friends think of her, and she doesn’t want them to hate her because she’s afraid of ending up alone again.
If you think about it practically too, May can be very screwed if she’s on too bad of terms with Momo. The better part of May’s support network is made up of Momo, Marigold, and Dale. And all three of them have every reason to side with Momo over May about pretty much everything. Since they’re her roommates as well as her closest friends, she could actually wind up homeless if they get pissed at her enough to kick her out.
