She's avoiding me.
Literal
She [topic-は] me [object-を] is-avoiding.
Compact and natural. The progressive ~ている here marks an ongoing pattern — not a single act of avoidance but a sustained behavior over time. English captures the same nuance with 'is avoiding' (not just 'avoids'). 避ける ('to avoid, dodge, evade') is one of those verbs whose meaning runs from the physical (dodging a punch) to the social (avoiding a person) to the abstract (avoiding a topic).
