Your question is confusing. You say you were in relation with her for years, yet you do not seem to have any inclination towards settling with her; then why this sympathy? Have you been playing with her emotions? Were you using her for your convenience? What is the reason that you are now yielding to your parents' wish? Is the new girl more beautiful and more rich? A lot of doubts are cropping up about you and your sincerity. Yes if you have been close to her and you now decide to get married to another girl, then I cannot blame her for her present behavior. She must be emotionally devastated. Under the circumstances, I would advise both of you to meet a Clinical Psychologist and discuss your problem with him/her. If you have a genuine reason for deciding to marry your parents' choice, you may explain that to the psychologist.. Meanwhile, since you say that your friend has already attempted suicide, you need to take her to a psychiatrist and get her treated, as a first priority. Otherwise she may attempt again, and this time she may succeed; and you will feel guilty for the rest of your life.

Your concern for her about her current emotional problems is in stark contrast to your lack of concern about your relationship with her all through the years. If you are not serious about your relationship with her then its not wise to indulge yourself in showing sympathy to her for her present situation. Just move out of her life and dont interfere with her life now...instead inform her parents about her current emotional state so that she can be rightfully taken to a psychiatrist for proper evaluation.

Maybe you were able to move on easier. That does mean she should also. She might take little more time to handle herself. Also for her to come to that stage I feel she can consult a Psychological Counsellor and get a clarity that how to move on and lead a better future.

Hello, As any relationship needs grooming and nurturing, there are times when relationships have to be given a closure. A proper and cordial goodbye, is at many times better than a sense of anguish and despair. I would like to believe that both of you must give your relationship a proper closure and must move ahead in life. Since both have decided in separation as the only resort. You must respect each other and the situations around you. However, it is easier said than done. In case situation gets difficult and if at all there are thoughts or ideas of self harm or ending life you or she MUST consult a mental health professional immediately. Help will be available, but you must take the first step. Take it easy and try and relax for now and be around people who are concerned about you.  Hope this helps you.. Best wishes for both of you..
