How can God help with family conflicts?
Love one another! How?
Should you cut some people out of your life? Try everything else first. But if what the other person did was horrible and they show absolutely no remorse – then steer clear of them. If you have no reason to expect anything to be different in the future, then diplomatically limit your dealings with them. Be careful to make this a last-resort choice. However, it's sometimes necessary to guard your own emotional health – or that of those you love.
