yes. you are doing the right thing for YOU... it is always hard to make life altering decisions, they are never easy. but you have to know, you are doing it for the best reason and that is to make yourself happy again. Your heart says to keep at it, your mind is telling you to leave and at the same time your mind is scared of what life may be like after and if your making the right decision... dont let your heart and head decide. Let the quality of life your living now compared to how it could be without the head games be you deciding factor! one of the best things my father ever taught me was, when your in a bad relationship.... "take love and emotion out of the picture and take a close look at what you have left" If what is left is unhappiness, arguing, bitterness, and feeling hallow. Then the time to make a decision has arrived.

I am sure without complications lingering in the air, he might be a good guy.... but like you said, even the best person can have mental and behavioral traits that 1- cannot be changed, and 2- lets them effect his whole attitude to the point he is mistreating the people he "LOVES" and the ones who love him. and after this long if he has not made any efforts to seriously get these problems resolved... then he will not do it at all, and will continue to beat himself up over it and underneath will hold resentment of you which will only create big issues out of minor things!!! And I completely understand how you would see an attitude change in him now that things are coming to an end. He might be upset and not know how to show it. However, i dont know him so all i can assume by what you have said about him is that this is another head game (my opinion) in efforts maybe to get you to stay because much like you... life after a long relationship is scary.. its almost like quitting cigarettes, its hard to picture doing everything you've done without the one thing there to comfort you, makes you happy, and has been there when you need it. but much like ciggs. a bad relationship can also kill you a little each day inside!!! (sorry, best analogy i could think of)

Take the leap... it will hurt a little but the sting of it will fade. you will always have a place in your heart for him but you will see your life improve. And when you start seeing you can be happy single, you will begin to ask why did i put up with it for so long!!!! I have faith that you will do just fine and you will get back to being you and enjoying the life you should be. You seem like a very good person and like i said previously... we all F*** Up sometimes... but we shouldn't have to pay everyday for it, and def. don't deserve to be treated with any less respect. we are all equal in this life and deserve to be treated lovingly and not hurt by people constantly!! Believe me, if i didnt see any potential in my future with my current partner.... I would not have tolerated it and would kick rocks before i let my anger come back and ruin a possibly salvageable friendship or even a reuniting later on down the road. That is the respect you give to someone you love... not treat them like an annoying child and brushes off your emotions. You may not want to do this but give it a try and after some time has passed and you find your happiness again... think back to this thread, and i will be smiling for you!!!!!!!!!!!!!!!!!!!
