To say nobody enjoys going through a break up would be an understatement. Even the best of break ups have more than their fair share of negative feelings. You both may agree it's best to go your separate ways, and even seem to be getting along rather well (considering the circumstances). Or...maybe the break up is down and dirty and it's a living nightmare. Regardless of how it ends up, the more advance notice you have, the better equipped you will be to handle it or possibly even save your relationship.
The warning signs of a breakup:
Avoiding each other
It's okay to want some alone time, but only to a certain point. It's also normal for both people in a relationship to have some idea of what the other person is doing. There should also be some level of interaction, even if you're not getting along all that well. But if either one of you are going out of your to avoid the other person, then that's a definite warning sign of a breakup. After all, you can't work through your problems if you never see each other.
This goes hand-in-hand with avoidance, but can take place when the two of you are together. For example, you may spend all day in the same house but never talk to each other. Or maybe you know something is bothering your partner, but they refuse to talk to you. If this is happening, then you need to do whatever you can to reopen the lines of communication.
While you shouldn't have any difficulty recognizing this warning sign of a breakup, you may not have as much to worry about as you think. As long as the arguing is focusing on behavior, and not getting personal or hurtful, then it's quite possible that you will be able to work things out. Nobody likes a heated argument, but at least it's an attempt at some form of communication, and that means there is a glimmer of hope.
Sudden changes and odd behavior
If your partner used to be quiet, but now all they want to do is talk; if they used to like to come home right after work, but now they're working as much overtime as they can; or if they are giving extra attention to their appearance then it's a sign that something is going on. Does it mean a break up is on the horizon? Maybe, maybe not. However, sudden changes in behavior should be enough to be more alert to what's going on in your relationship.
Once you know how to recognize the warning signs of a breakup you can take action start turning things around. Whether or not you try to work things out is entirely up to you. But if your relationship should ultimately come to an end, at least you will have had a chance to make it better. At the very least you won't be surprised. Either way, stay alert for these warning signs and do what you need to do if any of them should happen to come up.
