My sons father has negatively impacted my son because of his heroin addiction. My son is now five and expressing the pain he feels from his dad. His dad was in and out of his/our lives b/c of his addiction until a year ago when I cut him off. A year later he was 90 days sober and I let him back into our lives. Surprise surprise he began to use again and live an unacceptable lifestyle. Now my kid cries for him, acts up in school, has gotten expelled twice, has to go to therapy. I fucking hate heroin and I hate what it did and does to my sons dad. The pain never goes away and now I know my son feels it to and it enrages me.
