Dating A Recovering Heroin Addict

I've been talking to this guy for about two months now who I really connect with. We get along great, we are basically the same person but I just found out that he is a recovering heroin addict. I knew he had some drug problems in his past and he lost his way for a while but when I started talking to him two months ago he had a good job, college wasn't his thing so he only went for two years (which is okay school is not for everyone), he went to the marines but hurt his back during boot camp and then got a great job. A couple weeks into us talking he came across a great opportunity and quit his job now he works and interns for two different very big companies helping guide people on the path to recovery from drugs and basically giving speeches and really getting involved and trying to help. He is an amazing guy and I can see someone like this in my future but my parents are very upset with the fact I am falling for someone who could relapse at any time with not only any drug but with one of the worst drugs, heroin. Yes.. Since I've found out its all that has been on my mind... Thought after thought If I should get more involved then I already am.. But then when i speak to him all those doubts go away he is everything I could ever want In a person I'm not saying he is my soulmate or that he's the one but until someone else comes along and proves me wrong he is definitely someone I would want to share my life with. But I just don't know what to do about everything I have learned. He is only a year clean and very rarely ever drinks and it really seems like he has his life together but is this a risk I really want to take.. Is this the path I want to go down knowing what I do about him?
In your heart you know the answer to this.
You just have to do what you know is right.
You can't have it both ways.

All the best.
