I've been married for 21 years and have two kids(19 and 21). Having trouble with the younger one. He's been trouble all his life. I feel like my wife and I are just live-in babysitters. We no longer have any sort of intimate relationship. Honestly I'm no longer attracted to her and she's probably not attracted to me either. I wish I could go back in time and undo everything. I'm afraid of divorce. I am the type that doesn't like change but none of us are truly happy. I don't know what to do.
