Unfortunately, sometimes, when we are dating, or going out with another, we are finding out if we really are compatible together as a couple in the long run.
As your boyfriend want's to break up with you, he obviously regards you as not being the one for him.
This is only natural, & sometimes can hurt the burnt partner. You!
Instead of fighting for something that is not meant to be, dust yourself off & go out & find the one!
You may have to have many relationships before you find him. But that's what it is all about & perfectly natural.
Love hurts. (Only sometimes though) But don't waist your time & energy in chasing lost causes & what is not meant to be.
If you fight, to only stay together, in the long run, the heartache will be even more painful than it is right now.
You are meant for someone, someone special, as we all are. When you release your old relationship, you will therefore become free enough to attract the right one.
