Mental abuse

Not so long ago, I got my daughters dads Claire’s law back, now he tried to fob me off with he’s got it because if mistaken identity. So I got a call from the police. What’s on there isn’t particularly great. He does pose at putting our daughter in danger and myself. My daughter is 5 months old. At the moment it’s supervised contact only. A few weeks ago , he asked me to bring her down to where he lives to meet his family, so I did. The whole time, all of his family were ganging up on me. I felt very uncomfortable in the situation. My daughter was unsettled, as she was needing a nap, all the time I was trying to settle my daughter, they kept interfering and saying she’s not trying to sleep, as her mother I knew she was ready for a nap as she was fighting it. Her dad has messaged this evening to ask if I’ll bring our daughter to where he lives to meet his family and great grandparents. I feel very uneasy doing this. I feel sick to the stomach. Any advice.
