Does Your Spouse Need To Give You Heads Up If Their EX Is In The Room?

Leo & Rebecca In The Morning, BUZZ QUESTION: Does Your MAN or WOMAN NEED TO GIVE YOU A HEADS UP IF YOUR EX IS IN THE ROOM??
Me and my man went to a party and a girlfriend of mine told me my man's ex was at the party as well. I asked my man about it and he said HE DIDN'T WANT TO BOTHER ME WITH IT...Shouldn't he have told me his ex was at the party??
