Texting someone past midnight consistently could indicate several things, but it doesn't necessarily mean that the person has romantic feelings for you. Here are some possibilities to consider:
Friendship: They may consider you a close friend and feel comfortable reaching out to you late at night.
Night Owl: Some people are naturally night owls and prefer to chat late at night. It might be their preferred time for social interaction.
Convenience: They might have more free time or feel less distracted late at night, making it a convenient time for them to chat.
Loneliness or Boredom: They could be feeling lonely or bored, and reaching out to you past midnight is a way to alleviate those feelings.
Time Zone Differences: If you live in different time zones, what is late for you might not be late for them.
Flirting or Interest: While it's possible, late-night texting alone isn't a definitive indicator of romantic interest. Other signs and context would be necessary to draw such a conclusion.
To understand their intentions better, pay attention to the content of the messages, the frequency of communication throughout the day, and any other signs of romantic interest or friendship. Communication is key, and if you're unsure about their intentions, consider having an open and honest conversation to clarify their feelings and intentions.
Remember that each individual is unique, and there's no one-size-fits-all answer. It's essential to respect their boundaries and be mindful of their feelings and comfort level in any communication.
