Ox Leo woman and dog Capricorn man--bad relationship --prospect for managing relationship!

We Ox Leo woman and dog Capricorn man have 2 young children together (boy monkey Aquarius and girl Ox Virgo).

We do not get along at all, are divorced but must interact frequently due to children. How can I (what will help me) to survive interacting with this dog Capricorn who is mean-spirited and hostile to me? How do I survive and not let this deplete me physically, psychically and emotionally? I am fearful and anxious in dealings with him and need to know how to survive next 15 years. Thx
