We know there are boycotts in marriage, both from the man and from the woman. 
I call them '8-hour divorces'.

Being a man, I will naturally speak about sexual boycotts by the wife when something upsets her. 
For some women, a boycott is proof of repulsion or a last-resort, for dealing with major difficulties, 
while other wives use sexual boycotts like a remote control device. 

So how should a husband respond? What are his options? First, let us define the phrases ‘marital fidelity’ and ‘marital infidelity’. 
In my opinion marital fidelity has two manifestations: 
1) Not having sex with other people 
2) Having sex with your spouse. 

Likewise, marital infidelity has two manifestations: 
1) Having sex outside the marriage. 
2) Sexually boycotting one's spouse. 

Here are two options: What if, the affected husband responded with a boycott of his own; 
say, boycotting a relationship with his in-laws? 
What if the husband told the wife, “When you want nothing to do with me, I want nothing to do with your family. 
I made no vows to them when I married you. I owe them nothing but to love you. 
If you don’t love me, then they and I have no reason to see each other. If I don’t have your ‘skirt’, how do I have your heart? 
Tell me why I am so unimportant to you.” 

The second option involves legal separation for sexual abandonment. 
Here is what the New Testament says about marital separation: 
1 Corinthians 7:10-11 
“To the married I give this charge (not I, but the Lord): the wife should not separate from her husband 
(but if she does, she should remain unmarried or else be reconciled to her husband), and the husband should not divorce his wife.”
