Two older same sex women. Had a head on collision. Wife began drinking very badly for 3 years, became abusive, threats. I left the home after she became AbusiveI. She left the next morning with the dog. Takes him when she wants. Tells me when I can have him and makes threats to keep him. She has agreed to divorce. I want to keep my stuff and don’t want her to have any access to my pension or inheritance in the future. How can this work with access of our dog to share. Becomes very agitated when i don’t do what she wants. We are only renting. She had left me to do everything in the flat. Says she can not do things yet says she she lifts her scooter in her car.
I just want to clear things up and divorce ASAP. She said she will sign paperwork. How long will it take to get a divorce? Can I get to keep my dog half time?
