I was in a relationship with a heroin addict for 8 months. I have not heard from him in a month. I have been in other upsetting relationships. Currently I am in a relationship with the most genuine man I have ever met. It was hard for me at first to let him in. But I did. And being in this relationship has only brought me joy. There are great people out there. And as long as you are happy with yourself u can be in a healthy relationship.
