Completely stuck with an abusive ex-partner

I’m stuck. I’m currently in a hotel room in Blackpool with my children having come here with my ex-boyfriend. I have paid for us all to go to the circus, my bf has gotten drunk and chased me around the hotel room threatening to “break my jaw.”

I need help.

I have moved into a flat with him because I have nowhere else to go- I need help. I am autistic and I’m scared. I am desperate. I hate doing this and it’s embarrassing but I don’t know what I’m going to do.

The rent is due soon (£1250) and I don’t have anywhere near enough.

I have only just moved my two children into a new flat and now we can’t afford to stay there. I just want my children to be settled for a few months before having to move them all over again/go through the rigmarole of trying to find somewhere else to live. I am so tired of existing this way.

He has beaten me up in the past and knocked out my front tooth.

I have brought my children out for an evening in Blackpool which has turned into a harrowing mess, the three of us are sitting in a hotel room crying.
