How to deal break-up situations?

Hi everyone,
This theme is going strongly in my life now. Because I believe many brains together are better my own brain, I need you to share your advices about break-up situations.

One is love relationships and other is friendships.. How to deal good this kind of situations so that both persons would avoid to feel enormous pain..

My friend is now in the situation that she wants to break her current relationship. She has been with this guy over 1.5 years. They know each others very well and she finds it difficult to end the relationship. She doesn't want to cause pain to him.

So, my request was to share some ideas and experiences about break-ups..

Also...how do you end a friendship? I have some friends I used to be very close with but now things have changed totally. They treat me very unfair so I want to cool off the whole friendship..

For this love situations...I have found some people start spreading rumors or talk only bad about their ex to friends who knows him after break-up and I think it is absolutely stupid to do..

And is it possible or does it really make sense to stay as a a friend with ex?

And big THANK YOU for people who wants to share wisdom and experiences...Thank you..

The Fallen Mod: Thanks for answering. The thing is my friend really cares about her boyfriend. He is like a familymember. But she says he is not Mr Right for her. She said she has really good relationship to his sister and mother. She is worried about how their breaking up has affect on their relationship. Also she is wondering how the friends they have in common gonna react. I think breaking up, specially on her relationship is a little complicated.

Revenge is not good or healthy act. A lot of negative energy is the air. Some people only remember the bad part of relationships in the end. It is sad because every couple has some good moments together..

But if you be friends with your ex, is it possible that relationship can feel a bit odd...I mean for example if he would have a new girlfriend and you wish all the best for him but same time you feel some kind of jealous to this new girlfriend even you would never want to be together again...

Is it that this kind of friendship with ex...should happen only after both of you have get over the relationship.. After breaking up there might be too much feelings in the air still...

Another hand...maybe some cases it is better not to stay in touch if it is hard to get over the relationship and move on in life..

Sorry if my ideas sounds very messy, I am very stressed out and confused about life and stuff right now. Maybe I am even having a crisis.. :P

Anyways, I am all ears now listening any piece of wisdom..

Idk. maybe ur friend should try to cool off their relationship altogether for a while, and then when they've had some time apart, maybe started dating again, then they might consider being friends.

As for your friend-break-up issue, i think u just need to be truthful.
