Is it a good sign if a guy opens about to you about his problems?

I’m wondering if it is a good sign. Or if guys just normally do that with any girl. Because I recently started talking to a guy. He opened up to me about past traumas. Things he went through over the years. Relationships that didn’t work out. He explained why they didn’t. Also he told me of one time he used a person because he was going through things (Which he stopped doing that and new it was wrong of him to do). He just explained what he went through and how get got better.
