Emotional problems: the ex-girlfriend is now talking about a new object. Why does she always send me messages and call me every once in a while?

From a woman's point of view, she just wants to seek a kind of psychological comfort. It also reflects from one side that you are very important in her heart. Moreover, it is also a reflection that she actually depends on you. I think you shouldn't care what she thinks at first, but ask yourself how you really feel about her. If you feel like starting over with her, you can tentatively ask her attitude. If not, consider her an ordinary friend. Why do you care so much about the identity of your ex-girlfriend?
