Jonathan,
@Jonathan95 , the situation you speak of has been on my heart and mind for a while. It makes a big difference whether she is a believer or not. If not, it may be harder, but there is still hope; the God with whom we have to do raises the dead to life. If she is a believer already, there is more hope.
A crucial thing is that you be able to communicate with her – and she with you. It's when there is no connection is when things can go from bad to worse. This is why the question re being a more Christlike husband I suggested can be helpful – as if it
is you that she reacting to, she would likely take the occasion to let you know about it.
And even if not you, there may be some trauma in her past that is now coming to the fore – feeling safe enough to act out what she is troubled by – and you may find yourself in some drama you had no part in, even though it seems to be directed at you now. It may be that the Lord has you in her life to rescue her from what torments her – the Spirit of Christ in your heart enabling you to love even when she is unlovable. For a genuine Christian woman to act like that there has to be a deep root of anger, hurt, mistreatment, and pain welling up. For if she
is a Christian, you will have an Ally in her for her healing.
And even if not a Christian, she may be deeply responsive to you if she senses you mean her well despite the abuse she dishes out (an old axiom; hurt people hurt people). That may even be shocking to her. And loving someone clearly undeserving of love (is this not the case with all of us who are saved?) will be an occasion used by the Lord for your own growth in sanctification and godliness.
Don't give up on her. Seek understanding. Patience. Compassion. All the unexpected things in such a situation. Show her random acts of kindness and care. What does she like? Dinner out? Help with chores in the home? Encouraging words? Are there any things you can praise and thank her for? Surely she does have some good qualities.
Be Christ to her.
