I have been successful but in a different UK country where the law is different. I’d get in touch with a specialist law organisation eg rights of women for advice https://rightsofwomen.org.uk/. Any abuse should allow the partner to be excluded from the home. I was afraid I would not get my court order so i gathered as much evidence as possible. Made recordings of his abusive behaviour, saw my GP and womens aid to report what was happening and the impact on me, kept copies of text messages etc, told a trusted friend as abuse happened. I was able to show a pattern of abuse backed up with letters from GP and WA. Don’t give up. Just get prepared.
