Breaking up is an emotionally taxing ordeal to endure for some people, especially if the relationship was very serious. If it was a marriage and a child or children are involved, many people feel it's worth a try. Relationships end for many reasons, some as simple as incompatibility and some as complex as infidelity. In the world of romance, sometimes things go awry, and you find yourself single again: back at square one. If you both chose to part ways, it may not be as confusing or painful as when someone breaks up with you and you didn't see it coming. Some people may reconnect due to lingering feelings. If only one of you truly has feelings, then you may be the one that's vulnerable. You may have to assess whether are not you are actually reconnecting or just hooking up. There are many things that must be taken into consideration.
