How come after every failed new relationship, a guy will go back to the same ex? Because he realizes he truly loves her or because he knows she will allow him to come back? Whether it be just for talking, hooking up or getting back together?
My ex never told any of his exes when he was in a new relationship, he never told me either but I found out he dumped me for another girl anyway. When it didn't work out with her, he just came straight back to me. Looking at his relationship patterns, he was almost never single because he just stayed with his girlfriends (even though he didn't want to be with them anymore) until he met his next girlfriend. That is what he did with his ex before me and then with me.
In my case, my ex would come back to me just to keep him company. But I think there are some guys out there who will go back to the same girl time after time because he does want to be with her and has always had feelings for her.
Every case is different, but unless the guy says he still has feelings for you and wants to make it work and actually tries to fix the problems there were before, don't take him back.
The rule should be rewritten to state that people do not change their ways easily. Their egos are like inertial gyroscopes; they are constantly spinning in one direction and are rather difficult to move. Secondly the rule to remember given the latter is that once the relationship is over it is over.The embers of the relationship may smolder but they do not quickly rekindle a once brilliant fire.
I think it is familiar territory. They know what her threshold is when it comes to them. They know what lines they cannot cross and that is comforting. Sometimes men (and women) will stay in a relationship or even go back to one only because they are not ready to start the whole process over again with someone new. Most of the time they are just settling and have indeed fallen out of love with the person. That type of relationship ends up being either a roommate or best friend situation in the end. It's heart-breaking for the individual who is still in love with the other.
