Dating someone who has been married

My boyfriend of 6 months had a crazy past and although he's 23 he was married in the past and had a child in that marriage... He's been divorced for 3 years before we met and started dating but I'm only 20 and I've never dated someone who has been married and has kids... Any tips on how to deal
With situations and how to really understand cause for example his child doesn't live with him and I can see the toll it has on him & I feel like I am overstepping my boundries by asking questions about his ex wife and his child ... Should I even try and make it work? Has anyone experienced this before? Is there hope ? Cause I really care about him and I like him
