When I came back from other places, I made a dynamic. My ex-girlfriend commented that she would invite me to dinner another day. What happened? Talk about opinions

There are several possibilities: first, the ex-girlfriend still cares about you, and wants to take this opportunity to contact you after knowing your latest news, indicating that she either has your memory in her heart and is not willing to break up in the past. Second, she is purely out of politeness, or there is something that needs to be communicated with you, which has nothing to do with emotion. After breaking up, a girl remembers you and is willing to keep in touch with you, which shows that your previous feelings have not been hurt by breaking up. At least the reasons for breaking up are not so close. It's good that couples can't be friends!
