In college, I had a roommate whose world shattered every time she went through a breakup. She always blamed herself, couldn’t cope with being single again, and ended up convinced she was at fault. Most of those breakups were with the same on-again-off-again boyfriend.
It wasn’t just the one roommate either. My second roommate was self-obsessed. She partied at least four nights a week, modeled for fashion photography, and regularly posted pictures of herself holding champagne and dressed to kill. Despite appearances, she was suffering from bulimia and feelings of low self-worth. She flirted with men for validation and then couldn’t figure out why they never stuck around.
The first roommate would get back with her boyfriend shortly after each breakup. It never worked out. The second lived in a cycle of obsession and disappointment with her boy toys.
