Stay because of the kids or not

For someone who believes in the sanctity of marriage, I would do my best to resolve the issue first. Besides the reason why you married your partner was probably because you loved him, right? Somewhere along the way, you experienced challenges that tested your marriage. And sometimes, these challenges can become unbearable that we decide to go the easy way out. Maybe I would try to go back and ask myself first, what happened? Why did the love fade? And maybe, there's still something both parties can do to rekindle that love.
