Sit back, listen and pay attention to body language.
He has to wait for something? What's his reaction?
Waitress messes up his order? What's his reaction?
What does he talk about other women like? Sisters? Mum? Exes?
How does he talk about work? His colleagues?
As you build a picture of him, how would you categorise him? Is he honest? Is he guided by his moral compass? Does he help people?
Is he kind? Does he seem like someone who would take advantage of others?
I sat back and listened to DH when I met him... two things that I think really stood out to me was when we first met, he tried to pick me up, I squirmed, and fell out of his arms onto my bed which broke. He came back a few hours later with a toolbox and fixed it. I didn't ask. He was mortified at tge idea of having broken something of mine.
Second thing, he was doing something in his van, someone came and asked for help. He shut the door, somehow with the phone inside. He mentioned his broken phone, and just said, someone needed help, I forgot what I was doing for the moment... it seemed so kind.
He was kind to DD, he was kind and helpful to his parents elderly neighbours, infact waited for an ambulance with the old man next door who couldn't be moved due to injury, so was late for one of our dates.
He's an excellent husband and father. I wouldn't always say he makes the best choices in life, but the man is unfailingly kind to people.
