problem??

just now i was chatting with my 'adik angkat'. she told me that she was very confused. then, i asking her why she will so confused?
she told me that she was crushed on her cousin. she met her cousin when she n family attend her relatives wedding. they both was exchange their phone no. from that day, her cousin everyday calling or even message her. so her cousin requested her whether he can be her friend?
so she didnt think so much, so she say ok. everyday they chit chat via phone. on 1 day, her cousin asking her to hang out with him. but for 1st time, she rejected it coz she dont want made any misunderstanding.
but for 2nd time, she say yes bcoz that time she was very boring at home. so she want going out to have some walk. bcoz she say yes, she started had some feeling on her cousin. she say she so scared coz she really worry that the feeling is true.
the problem is she had a boyfriend!!! now her boyfriend was at national service. she dont want let him go coz she still love him but at the same time, she also had a feeling on her cousin. so what suppose i say to her??
i also dont know how to solve her problem.
bcoz for me, love relationship really troublesome... so if can avoid it, i will.
i really cant help her...
i'm so sorryyyyy.......:-(
