Would you please give her some suggestions?

Would you please give her some suggestions?She is now together with a boy whom she has no feeling for,while on the contrary,she is always caring much about the one whom she used to go with.She wanna go to him when told about his true feeling for her,but she is hesitating and in a dilemma,because she is not willing to hurt the present.She is wondering what can be the optimum solution.Many thanks!
