Most of the time, it's obvious when your relationship has reached a rough patch. But for married people who have taken vows that end in "...so long as you both shall live," it can be hard to let go of a marriage, at least not without a fight. Take a look at five signs that indicate that the damage done might be irreparable. First, take a look at how you connect...if at all. Having a sense of disconnect where there used to be intimacy might indicate that you're going through a rough patch. When you're physically not together and don't really have a problem with that, it's a red flag. When you don't mesh on issues in which you used to be in sync, like kids, money and activities, these may be symptoms of disconnecting from one another.
