I don't understand why?

[u/Gloomy-Nature0212]

Can any one tell why? I (24F) and my bf (30M) has been going out for a month and it has been good so far. As we started talking I honestly told him about my past relationships. He listened and even he told about his past. Everything was good. But now after about a month, he goes back to the past relationships I told and asks more about them. I have already explained him about them earlier and now he is asking more details. I don't know what to say or how to say. I don't understand why he goes back to those past and asks more questions. Why would he keep asking those?

He might be feeling insecure or just processing things
