How do i break up with my girlfriend without breaking her heart?

i've been going with this girl for at least 4 months and yes i used to love her but she nags to much. i've already broken up with her twice and the third time we got back together i told her i wouldnt anymore. but now i really really regret saying that and i know if i broke up with her she might kill herself like she did last time!!!!!

You have to understand that with every break up, there is pain to be experienced. It is simply unavoidable. Best you can do is be as gentle as possible, letting her know what while you cared for her, it is best for both of you to go your seperate ways because things just aren't working out. Be prepared to get peppered with questions like ';is there someone else'; and other stuff, but just stand firm. She will get over it.How do i break up with my girlfriend without breaking her heart?
The point is that, you do not really love her. you have gotten what you want, now you can give excuses. You know why? true love counts no error. if she nags, call her tell her what puts you off. address each other differences after all there are no two people that are completely identical--- we tend adjust. if she is serious that nobody will have her if not you, she must be seriously in love. so, love is not for break up.fine tune her, she might be the lucky lady of your life.
dont blame yourself if you need to break up do it now and dont wait
