Glad to hear you got away from drugs and are focusing on your daughter now!

But yeah you have yourself and your daughter to think about. Maybe it would be best to get to know him better and take things slow. Then you can see if its drugs or if hes just nervous about the relationship. Maybe you can sit down and talk to him....and ask him if hes using anything. Don't do this right away because most users usually deny it. But wait until you two know each other a bit more.....and then just ask. Don't act like your directing it right at him. Just say that you used to use...and its very Important for you to date men who don't use drugs. Just act like its something you ask every guy you date.... I mean either he will tell you yes or no. At least put it out there how you feel about drugs and how you have no tolerance for them.
