I think that was selfish of them, if she is only 14 and only sees them one night a week then surely they could resist for one night. They are married after all, it's not like he's just met her. A similar thing happened to my daughter too and my ex was so not understanding of the situation (sorry, bad grammar) it escalated and my daughter no longer sees her dad. He always put the needs of his wife first and my daughter got more and more pushed away, she is older now and doesn't even miss him. Serves him right I think, I never interfered, it was purely her decision.
