had i done the right decision?

You're already listing her faults and you're painting it such that you are miserable in the relationship. If this is indeed what you tru;y feel, then you've already answered your question. I know that initially after breaking off, you might think that maybe it is your fault and that you could have done more to change her. Do not feel sorry for yourself. I know coz I have also been hurt before.

well congratulations, if you have openend your mind at the earliest than to sacrifice yourself, family and friends for her. you will find a better lady than her who understands, respects you and who is not selfish. good luck

Of course it is the right thing to do. Who needs torture and someone else ruining your own life? Well, if she treasures you, she would have tried harder to keep the relationship and change her attitude of things. I think you will be better off without her. I think daily life is complicated enough to have someone else adding more complication and tireness to us. I wish you very good luck in the future!

yup, you have only made the right decision. It's useless being with someone like her. There are still a lot of better girls than her. Am just wondering how'd you like her...lol
