how to help

My best friend went back to her emotionally abusive, toxic man (of 3 years) near the start of lockdown. He’s a drug dealing, narcissistic scumbag. I’ve not heard from her since, which is unlike her. When I reach out, she says she’s “dealing with some stuff” and “doesn’t want to talk about herself.” She has poor mental health and her Grandma passed away from Covid. I hear about the rise in domestic violence and my blood turns cold. My police friend said this awful man fits the profile of domestic violence, has definitely physically hurt her and perhaps that’s why my friend has kept me away. I worry about her so much. I miss her so much. I wish she was there for me during my hard times this year even though I know she can’t be.
