sorry you’ve had to go through this—it’s not fair at all, and it’s no wonder you feel so lost. The most important thing right now is your safety and mental well-being. If your home environment is toxic and unsafe, it’s entirely reasonable to want to leave. However, moving to another country, especially to live with your boyfriend, is a big decision. It might be helpful to think about a few practical steps first: are there resources or organizations in the UK that can support you? Women's shelters, charities, or local councils often have help for people escaping abusive situations. They might even provide temporary housing or guidance on your next steps.
Running to Germany could seem like a way out, but it’s worth considering if it would give you long-term stability or add new stresses, like managing your exams and adjusting to a new life all at once. Retaking your A-levels is a huge deal, and completing them could open doors for your future independence. Maybe there's a middle ground—finding a safe place in the UK to stay temporarily while focusing on your studies. You deserve to live somewhere safe and supportive, free from the fear your dad’s actions bring. Whatever you choose, you’re not alone, and there are people and resources that want to help. Please take care of yourself and don’t feel ashamed for needing support—you’ve already shown so much strength by reaching out.
