Does it always signal a red flag when your boyfriend busy an ex-girlfriend jewelry?

You mean buying an ex jewelry? YES!

Hello.

A red flag YES... Any time a Man buys an ex anything you need to open your eyes. Does it mean he is cheating NO. BUT you need to do some checking on it for yourself. Even if you think he is being honest you need to make sure his EX knows she is just a friend also.

Good Luck
