Dream about an ex. What does it mean?

I have a dream about my ex and basically he was crying over me and his sister was showing me his phone like proving he speaks to no one other than me (I find this weird because I’m the past he cheated and I got scared he would do it again and finished him and he cried to be and proved to me that he had no other girls that he was speaking to and that he had changed) it seems very realistic and I’m wondering if anyone knows what this could be symbolising.

Baring in mind he has asked me back recently and I’ve had mixed thoughts 🤔
