Here’s a Jain Dharma–based way to handle this with calm and clarity:

• Keep ahimsa (non-violence) in speech and thought. Don’t react with anger, sarcasm, or accusations. Instead, speak softly and honestly about how you feel.
• Practice satya (truth) with compassion. If you’re worried or hurt, name your feelings without blaming her. For example: “I felt a bit sad when I didn’t hear from you this morning. I value our communication.”
• Cultivate maitri and aparigraha (friendly, non-possessive attitude). Don’t read this as a personal rejection or a test of loyalty. Relationships require mutual space and understanding.
• Avoid jumping to conclusions. There could be many reasons she didn’t message—busy day, something urgent, or simply forgetting. Give her the benefit of doubt.
• Check your own expectations. If you rely heavily on daily messages for emotional balance, reflect on that preference and communicate it calmly, aiming for a healthy pattern that works for both partners.
• Focus on pratistha (steady conduct) and samyak darshan (right understanding). Remind yourself that a single missed message isn’t a measure of the whole relationship. Keep your mind steady (samadhi) and respond with patience.
• If the issue recurs, have a sincere, non-accusatory conversation about communication needs and boundaries. Seek a solution together rather than “winning” an argument.
• Remember the core Jain aim: gentle living and non-violence in all aspects of life, including how you speak and treat others, even in moments of doubt or hurt.

In short: respond with calm, honesty, and compassion; avoid blame; communicate your feelings; and work toward a mutual, respectful approach to communication.
