Past betrayal can make a new relationship feel dangerous even when the new person has done nothing wrong. Someone may check, withdraw, accuse, test, or leave early to avoid being surprised again.

What sabotage can look like in a new relationship

Healing does not require blind trust. It means distinguishing present evidence from past fear. A new partner can be asked direct questions and observed over time without being forced to prove innocence every day.
