single pregnant mom quarantine

Six months pregnant with our second child. Toddler is 3 yrs old. Baby daddy refuses to support us financially, does the bare minimum otherwise, and is a cheating lying fraud. About 3 months ago he moved into his parents house 30 minutes away. Entering my 3rd trimester stuck inside with a destructive toddler with my nearest family member a 4 hour flight away has turned me into a hopeless, depressed, anxious mess. Add to it that I’m out of work and my electricity was shut off twice this year. Debating risking my health and my kids health by flying to Colorado to live with my sister.
