what if you betrayed by your patner?

It all depends on the level of the betrayal, some I will forgive while others I will not forgive. I have not had an experience where I felt seriously betrayed.

All my exes betrayed me it seems to be normal for a man to do it and think his partner doesn't know (men still seem to think women don't see it or feel it and they believe all their lies). To make it short: it did not care anymore, I told what should change, gave them a certain time (1 year) and as nothing changed (only for a few day) I left after that time. Only if you accept this behaviour and accept to be treated like a piece of dirt you will be hurt. Since you are the one who accept this, you are the one who allows others to spit on you, stab your back which is not great for your self esteem. So if you want a great life, great relationship you have to know who you are, what you want, what you will accept and say NO or STOP if there is something you can not accept/live with. If you don't do that, are too afraid, can't find the courage or strengh for that and accept you also have no right to complain. Since after all the first one you are responsible for is yourself.

I also think it would be bad to betray by the partner. I think pain in love is one of the hardest feeling of hurt one can feel. I think this wound would take long to heal. I think most times would be shocked. I wonder why people betray in the relationship especially when they get a good partner. I think most times the pleasure of mind is better than pleasure of mind and I should not try to hurt others.

It happened to me once, and I ended the relationship. I don't think I can forgive something like that. I would always pop up in my mind and the relationship wouldn't work. After a while I got over it and started talking to other girls, I went to the gym and burned some extra calories. At least that was productive :)
