First, it isn’t clear if your friend or her husband are Christians and that makes a difference both in their mindsets and in their ability to take guidance from God and from godly people. She is in a difficult place and must feel abandoned and rejected. She could use some counseling for sure. In reality, her husband has deserted her, and though I know nothing about their marriage, I can tell you that this alone goes against everything in scripture about how a husband is to treat his wife. If this is a pattern, then nothing will change until he wants to work on the marriage with her. This behavior must stop. She doesn’t need to have a victim mentality – she needs to communicate her feelings to him and tell him this behavior is unacceptable. He must make a choice. At best he is being childish and irresponsible, at worst he may be cheating on her and depending on her continuing to accommodate this. None of this is God’s will or His fault. We live in a fallen world, we depend on Him to give us strength to go on, strength to do what is right, strength to do the hard things in spite of temptation. Our part is to ask for His help in a world currently run by the enemy. I pray she will feel God’s love ad comfort. Please let me know if she needs a referral to a Christian counselor. My prayers for strength, comfort and wisdom go out to her.
