Please help, best friend dating a heroin addict who's in and out of prison
I'm going to try to make it short.
They meet and immediately start dating, a month later he proposes before he goes to prison. She would be at my house every day, happy, bubbly, etc, since they'd been together she barely spoke to me. Never came around, was miserable when I did see her (we have class & work together) and never had any money even though it was always like her to manage her money well. He leaves once (prison), she comes around a little more. He comes back, she's gone again. He leaves again (prison), she comes back again and admits he's a user. While he was gone, she was around every day, started being herself again, was happy and the life was there again. She talked to me about everything and I listened. I stood by her side through it all because even though I wanted her out of the relationship, it was her decision. I even went to his court hearing with her. She swears up and down if he doesn't go to rehab the next day she'll leave him.
It's been a couple months. I barely hear from her at all. He's not in rehab. This whole time he's been living with her under her father's roof (shes 20, he's 34), no paying rent or anything.
So here's my real question: Last week she wore a shorter sleeved shirt. There were small bruises on her inner elbows. I didn't say anything, hoped to god it wasn't what I thought. A coworker came up to me very concerned, and stated (having been involved in nursing) that she was positive my friend had track marks on her arms. I freaked. I talked to her brother and told him everything. My mom (whom she was very close to) spoke to her dad. My friend texted my mom saying my coworker was lying about everything, that her dad says it was ridiculous someone would say that, the bruises are from wrestling, that I seemed like I didn't care, never try to hang out with her, and he's not using. The thing is, I supported her fully, then she withdrew from everyone again. She claims she's happy and when "he's successful and on top" we'll see she was right. I always asked her to do something until she withdrew again and turned it all down. How can I support her decision anymore when everyone can clearly see she is absolutely miserable again? I can't support that and as much as she thinks we're against her "happiness", she's completely wrong. I hope she's right and she is happy, I truly do, but I don't believe it for a second. Did I make the right choice in speaking to her family? I know I jumped to conclusions but as much as I've been through with this I don't even care if she hates me, if in the end I did my best to help her.
