Talk on Only Dating long enough to notice whether their story stays consistent. A person who will not stay on a video call, or who rushes the meeting, can wait.
Meet in a public place, in the daytime if you can. Tell a friend where you are going and when you expect to be back. Arrange your own transport there and home.
Do not leave a drink, do not share a bank code, and do not lend money. If the conversation turns to a crisis that only cash can solve, stop.
