It's been almost a year my ex broke up with me. We have been together for a substantial part of our lives and did almost everything together. She gave me to motivation to want to better myself when i was down .Safe to say i am in a better place now than i was before we meet but as fate would have it , she decided to call it quits.I will not go into the details of why she decided to split but mostly i guess it's my fault.

Most of the time we still talked to each other like before we broke up.Currently there is someone who is pursuing her ,someone who i see is more successful in terms of career and education than me. She haven' gave him an answer yet. Deep down i wanted the best for her. I just want her to have all the things she was longing for during our relationship which i could not give. Knowing she sometimes spends time with the other guy really hurts. I guess i still have feelings for her even after so long.
Problem is what should i do? Do i severe all ties with her and move on or just bite the bullet,continue to be friends with her but at the same time feel suicidal over the thought of her belonging to someone else?

The standard advice is to forget about her.But you can't just stop being friends with someone for more than 10 years just because we are not romantically involve any more.Anyone who is in a long term relationship will surely understand that.

Currently feels like life has no meaning.When everyone is already having family or kids,has settle down and i feel like i am back to square one. She was my goal in life.The person i want to settle down with grow old and die, but due to certain circumstances it wasn't meant to be. There are really worst things other than death after this experience. Getting dump,feeling hopeless and having someone who is better going after your ex can really make you feel useless  .Currently stuck in a rut and limbo. Nothing in life seems to make sense anymore. Death is not the answer but life is full of torture.
