How can get my ex girlfriend back even she has fallen in love with somebody else and i tried and promised?

there are no rules in relationships except those we set for ourselves,,your ex decided after many disappointments from you,that enough was enough so you cannot argue the fact she has every right to try dating different people,,you had your shot(s) and as you say,,blew all of them,,this to me would seem you didnt care enough about her when you had her,,suddenly deciding now that she is the one is all fine and dandy but why should she not date another man,,one who hasnt yet hurt her and may never hurt her,,doesnt she deserve some happiness and stability rather than uncertainty from you and your behaviour,,sit back,wish her well and make it clear you will wait,,,,,you may be waiting a long time but during that time i would suggest trying to be a man,,a grown-up,,one who knows what he wants and sticks to it,,she may give you another chance if she can see how you have changed but this you must do for you ,not her,,,someday there may be another woman and unless you grow up you will have this problem all over again.

I hate when women say that the ONLY reason they're still with a man is because they have a child with him. The REAL reason you're still with him is because you created a situation for yourself where you allowed yourself to be totally financially dependent on him. And you did this because you're uneducated, undereducated, unemployed and unsuccessful. If you had gone to college and had a good career, you'd already be gone.

I think you should leave well enough alone and hope that absence makes the heart grow fonder. Remember whats meant for you wont pass you by. may take some time but if your constantly in the fold then she may get ticked off. good luck!

You got a lot of chances and messed them up. What's she supposed to think? She's tired of the empty promises.

You had better learn from this. I say leave her alone and move on.

why do u hurt her so much? get over her n let her be carried by the wind n c other guys who wud less likely mess with her!

Move on and learn from your mistakes. Stop beating a dead horse.

Move on. She gone count your loses and forget about. learn from your mistakes though

wow. well, if she really has a boyfriend. but she might be lying to you just to get rid of you. i'd say just ask her you guys could be friends and keep in contact.

It wouldn't be right for me to answer that .....because you may end up in Leavenworth.

May be never; and I am sorry to say that.
