View this post on Instagram Instagram PostShe claimed that her relationship with Feldman was normal during her freshman year. However, everything allegedly changed in the sophomore year when Feldman began to "fixate" on her."And it was confusing, because the focus wasn’t like, 'You’re doing so well, let’s get you on the field. You’re going to be a starter.' It was all based in her wanting to know who I was dating, her making comments about my body and her always wanting to be alone with me," Alex Cooper continued.Cooper also recalled an incident when a boy she was seeing came to drop her off on campus, which led to Feldman allegedly calling her for a private meeting."She asks me, 'Did you have sex last night?' And I’m like, 'I’m sorry, what?' And she’s like, 'I don’t know if you should be sleeping off campus.' And I’m like, 'all of the other girls on my team sleep off campus.' I didn’t know what to do, and every time I tried to resist her, she would say, 'There could be consequences.' And there were," Alex Cooper claimed.In an episode of Call Her Daddy, published on June 10, Cooper explained that she decided to speak out about the alleged s*xual assault after a long time. She claimed that she discovered other women who stepped into the field have also endured the same alleged harassment she did."I discovered that the abuse and trauma I had been subjected to at Boston University was still actively happening on that campus is 2025, a decade after I left, and I spoke directly with one of the victims," Alex Cooper said.Meanwhile, the docu-series also features Cooper parting ways with Sofia Franklyn, the former co-host of Call Her Daddy.Stream all episodes of Call Her Alex on Hulu and Disney
