My husband and I got married for the second time. He tells me that he loves me. But he sent a message to his ex-wife saying: No matter where you go, you will always be in my heart. why

A woman attaches great importance to her first time, even a man who cares about her. Although he broke up, he still cared about her and hoped that she would have a good life. If the other man of his ex-wife doesn't love her, he will be very angry and will break up. He also wants her partner to take care of her more than he does, or maybe he just wants her to be well. You should cherish your husband's feelings and don't quarrel with him because of this. Go with him. If you have feelings, he won't want to hurt you. Emotional people are very measured in their sexual life. You don't have to worry that they are in the same room. He has become a family member of his ex-wife. Don't try to change this, as long as it doesn't affect your life, don't mind too much.
