My wife always likes to mention my ex-girlfriend. She will be angry if I don't answer, but I love my wife completely. What should I do?

There are several possibilities. First, when you are with your wife, your wife knows how much you used to love your ex-girlfriend, or you are still in contact with your ex-girlfriend. Second, your wife is strong and possessive, and there is no room for sand in her eyes. Third, maybe you are having an affair with someone else. Even if it is not discovered, women have strong intuition, so this is a reference for your ex-girlfriend. Fourth, your wife believes that you have nothing to do with your ex-girlfriend. She just wants you to prove that you love her the most, that is, to listen to your sweet words. Nothing more than these four possibilities. Those who say your wife is immature know nothing about women. But congratulations to the landlord, your wife really loves you, and I hope you will regard this as an emotional appeal, not a burden.
