Before the 90 Days thrives on emotional tension, cultural clashes, and relationships pushed to their limits, but few conflicts have drawn as much attention as the feud between Forrest’s mom and Sheena. What began as subtle discomfort has escalated into open hostility, leaving viewers asking one question: why can’t these two women get along?

At the center of the conflict is protection versus independence. Forrest’s mother sees herself as a guardian, someone who has guided her son through life and feels responsible for shielding him from potential heartbreak. From her perspective, Sheena is an unknown variable, a woman entering Forrest’s life quickly and under unusual circumstances. That uncertainty fuels suspicion, which soon turns into confrontation.

Sheena, on the other hand, feels judged before she is understood. Entering a relationship already under scrutiny is difficult, but facing constant skepticism from a partner’s parent makes it even harder. Sheena believes she is being unfairly scrutinized, her intentions questioned not because of her actions, but because of fear and preconceived ideas. This imbalance creates resentment that builds episode by episode.

The cultural and emotional gap between Forrest’s mom and Sheena plays a major role in the feud. Their values, communication styles, and expectations differ sharply. Forrest’s mother prioritizes caution, stability, and tradition, while Sheena emphasizes emotional connection, trust, and the right to define her own relationship. Instead of these differences being discussed calmly, they clash head-on.

Control is another key issue driving the tension. Forrest’s mom struggles with letting go of her influence over her son’s decisions. While her concern may come from love, it often manifests as control, especially when she questions Forrest’s choices in front of Sheena. This puts Forrest in an impossible position, forced to choose between loyalty to his mother and commitment to his partner.

For Sheena, this dynamic feels suffocating. She wants to build a future with Forrest, but feels undermined when his mother inserts herself into their relationship. Every comment, every skeptical look reinforces the feeling that she is fighting an uphill battle for acceptance. Over time, that pressure turns into defensiveness, which only worsens the feud.

Communication breakdown is where everything truly unravels. Instead of addressing concerns privately and respectfully, both sides allow emotions to take over. Forrest’s mom voices her doubts openly, sometimes harshly, while Sheena responds with frustration and emotional honesty. Neither feels heard, and each interaction adds another layer of misunderstanding.

Viewers can see that Forrest himself is deeply affected by the conflict. He loves his mother and values her opinion, but he also wants to stand by Sheena. His hesitation to firmly set boundaries allows the tension to grow. By trying to keep the peace, he unintentionally fuels the feud, leaving both women feeling unsupported.

Trust, or lack of it, sits at the core of their relationship. Forrest’s mom does not fully trust Sheena’s intentions, worrying that the relationship is moving too fast or is motivated by something other than love. Sheena senses this distrust and interprets it as disrespect. Without trust, every interaction becomes a test rather than a conversation.

The emotional stakes are high because this feud is not just about personalities—it’s about belonging. Sheena wants to feel welcomed into Forrest’s life, not treated like a threat. Forrest’s mom wants reassurance that her son is safe, loved, and not making a mistake. Both desires are valid, but the inability to acknowledge each other’s fears keeps them at odds.

What makes this storyline compelling is its realism. Many couples face similar struggles when families become involved, especially when relationships move quickly. Before the 90 Days amplifies these issues, but the emotions behind them are deeply relatable. Fear of loss, fear of change, and fear of being replaced all play a role.

As the season progresses, the feud raises an important question: can mutual respect be rebuilt? Resolution would require Forrest to step up and establish clear boundaries, his mother to loosen her grip and offer trust, and Sheena to remain open without becoming defensive. Whether that growth will happen remains uncertain.

Ultimately, the feud between Forrest’s mom and Sheena is about more than conflict—it’s about transition. Forrest is moving from being someone’s son to being someone’s partner, and not everyone is ready for that shift. Until that transition is acknowledged and respected, tension will continue to define their relationship.

Before the 90 Days uses this conflict to highlight how love stories rarely exist in isolation. Families, expectations, and unresolved emotions all shape the journey. Forrest’s mom and Sheena may be feuding now, but their story serves as a reminder that understanding, not control, is the foundation of lasting relationships.
