Why did he get divorced? Was he or she abusive? Did he marry the girl that he got pregnant? Drunken weekend in Vegas or a spur of the moment thing? There are a lot of reasons why people get married and for every one of them there is at least two or more reasons behind their divorce. So with out this information how can we tell you if you should be concerned? You are dating but yet you can't ask him the reasons for the marriage and/or divorce?

You don't want him to know you were looking around!! But I think you should wait for him to have the courage to tell you himself and hopefully explain it with a reasonable explanation. If he hasn't told you by the time things have gotten serious that's a red flag. Just keep it at the back of your mind
