Sometimes people are really disturbed inside. Feelings of anger, frustration, and envy often make friends blind. If your friend is true then they will apologize to you sincerely for bringing you pain and try never to repeat the incident. A strategy for dealing with people who are experiencing hardship and hurt is to leave them alone unless they ask for help or are in danger of hurting themselves. Dealing with emotional pain takes time; to sooth the spirit(mind,emotional state, etc) some people have to toughen up and mature. Many young people are affected by uncomfortable feelings because they are unaccustomed to internal sorrow and suffering. So the best thing for you and your friend is to give them space and some time to get back to the way the use to be(friendly). If they come around then welcome them. If they continue to hurt you... The friendship has turned to poison and you should part ways with them. Surviving tribulation and suffering will make you and your friend wiser and possibly strengthen the friendship. Well now ... I hope that you will find peaceful resolution to your friendship problem and know wisdom to protect yourself while soothing the pain of those who need you. So cheer up.

It depends on how many times this has happened before. If your friend keeps hurting you, it's time to say goodbye. Maybe your friend does not want your help.

i am strongly agree with Mr,George!!

I think it's better to good bye. Genarally, you friend wouldn't hurt you if he/she really care you, not to say hurt a lot.
