1. As an example

He hopes that you will be a more fulfilling relationship than his last one.

It’s possible that he is assessing you and the relationship he ended in an effort to think back on the past.

He draws parallels between you in an attempt to either validate your own growth or to motivate you to get better in the relationship.

Guys will keep you current by bragging about the good qualities of their former relationships.

However, if you give a guy the advantage he lacked in his previous relationship, he will talk badly about his ex.

He will want to tell you how much better off you are than his ex if you both possess the same level of energy that he was looking for in his last relationship.

2. To make you feel envious

He may talk about how much he still loves his former partner. He will discuss his excellent deeds for her and how he received a hard split as payment.

He thinks everything he said would make you jealous of his dedication to the collaboration. He interprets that as an indication that you want to know more about the positive parts of what he’s done.
