Friendship
Some days ago, I argued with my best friend, because she fell in love with my boyfriend, though we had broken up.  However, I am unhappy; I don't know if they have thought about my feelings, I don't know what I should do.

*am :  use for present tense   e.g.  I am unhappy,  I am feeling unhappy

*falled :  past of 'fall' is 'I fell' or 'I have fallen'.  It would be better to write 'she has fallen in love . . ' as it is a recent event.

*we broken up :  'we have broken up' or, as you are recounting the event as taking place before the situation you describe  i.e. you had already broken up when your friend fell for your ex-boyfriend, you would say 'we had broken up'.

*they are think of :  'they are thinking about . . '  or  'they have thought about . . '

It must be difficult to accept, but you should try to overcome your feelings of disappointment.  Time will help you to do this.  If you can keep your friendship alive, it would be a real achievement for you, of which you could be proud.
