AC/DC's 'Dirty Deeds' comes to mind:
You got a lady and you want her gone
But you ain't got the guts
She keeps naggin' at you night 'n' day
Enough to drive you nuts
Pick up the phone, leave her alone
It's time you made a stand
For a fee, I'm happy to be
Your back door man
Not that I would know who AC/DC are or would ever listen to them of course *smiles a cheesy greasy self righteous smile*
On a more serious note, you're the man. So man up. Take up your God given spiritual authority and close in on the spiritual issue involved and then put it to the sword. Examine yourself and look for EVERY possible area that you could be at fault, then, and ONLY then start to look for issues elsewhere. Be open and honest with your partner, for that is what she is. Your partner. Make your expectations of yourself and her clear to each other. Do so prayerfully. Then, be the man you're called to be. Tough enough to bring the situation to order. Keep your duty foremost in mind, ''Seek first the Kingdom of God and His righteousness'' ''Husbands, love your wives as Christ loved the Church and gave Himself for her''. Armed with weapons that are divine in power to demolish strongholds and exercising them with righteous wisdom, you will see results.
Keep us posted on your quest.
