I used to be a heroin adict, but then quit it when I started going out with this girl I loved to death. A few days later, she dumped me because I used to do heroin! What the fuck!?!?
Well,...
No one but yourself knows that you are a new man. She probably thinks that your risk of relapse is pretty high, and chances are that she's right.
I guess that to be more convincing you will have to prove that you can stay clean for a while, and deal with the problems that lead you into heroin consumption in the first place.
Frankly, you can't blame her for being scared, it's just an additional problem that you will have to deal with.
OP here, I want to thank >>2 you are a very wise person,
I just want to add in that she gave me a fake answer at first for dumping me, and then later on I found out from her friend that it was because I used to do heroin. I asked my former gf if that was true and she reluctantly said yes! Yet again... WHAT THE FUCK!?!? Why did she give me a bullshit answer? Why didnt she tell me it was about my past heroin addiction in the first place?
(I'm not 2, by the way)
She was probably just afraid that you would be extremely angry with her if she told you the real reason, especially since you've quit since.
Talk to her and say (assuming she wants to get back together): "How can I prove to you that I'm clean and will stay clean for you?"
Depending on her answer, you can decide whether or not the relationship is worth what you need to do for her. If she's worried about it and you value her enough, then you should invest a lot of effort into making her feel safe and content with the situation.
start using again and say it was her fault. that should make the bitch fell bad.
Don't do what >>6 says. (I know it's an obvious troll, but I want to say this anyway.)
I dunno, it sounds like fun. You might seriously break her.
Whatever you do or think might happen, just don't be a faggot by starting to use it again only because she did that
Why would you tell her you used to do heroin so early into a relationship?
Move on. It happens. And, being a former heroine addict does have a social stigma you will have to carry with you so you should expect these sorts of occurrences. I'm not saying that it is fair, justifiable, or reasonable. I'm just saying that we live in a world which has that stigma for whatever reason and you have to deal with it.
