You’re not crazy for noticing the switch. What you’re describing are classic pattern changes:
- Phone suddenly face down
- Hyper-responsive to others, unavailable to you
- Shift from “we share everything” to “you’re out of the loop”
Those are red flags, but not automatic proof of cheating.
What to do now (no spying needed):
- Slow down: Watch patterns over a few weeks, not a few hours. Is this consistent or just a phase?
- Ask directly, not accusing: “Lately you’re super private with your phone and I feel shut out. Is something going on?”
- Listen to how they respond: Do they get defensive, flip it on you, or calmly explain and offer reassurance?
- Decide your line: What do you need (more openness, shared passwords, regular check-ins) to feel secure?
You can’t control what they do, only what you accept. If the behavior + their answers don’t add up, that’s your answer.
