I'm American and had a baby with a British man. After 3 years of being here I want to go back home ( currently uk) to my family as I've been suffering mentally without them near since giving birth. My babys dad doesn't Want to move and keeps threatening suicide if I leave him with the baby. The need to leave is also him due to having mental illness like depression, anxiety and anger unmanaged. It's too much for me to handle with a baby. My baby dad and have decided the relationship is too toxic for our baby so decided to end it. I want to take legal action so I can take my baby with me, he isn't going to consent on his own free will. What should I do??
