Okay where to begin

I have a friend that I known for about 3 years

We met in a online game and friended each other on facebook and we been RPing (that was the first ever time I ever RPed)

I can say that our relationship is close enough that we consider ourselves brother and sister

During the time of the 3 years she had a boyfriend named (I'm going to use a fake name for him) Mike

They both live in the Philippines so this part can get.....confusing

So 2 weeks ago Sis (that is what I'll call her for this or Kaima) came to me with a problem

She suspected that Mike didn't love her and asked me for advice

Here's the thing though, I never dated anyone before therefore I am useless

She didn't know this

So I told her "sit down and talk to him about it." She did and they worked things out

A week ago, she came back with another problem

Her friend just confessed his feelings to her and started treated her like a girlfriend before she could reject him

She asked for my help and I gave the best advice I could give

She ended up ending things with Mike and went with (I'll call the friend Ross) Ross

Sis(Kaima) and Mike drifted apart so that's why she left him

Anyway

Not to long ago

She came with another problem saying that she still loved Mike

So I just said "follow what your heart say" she hasn't texted back since

So what I did was the right thing or I should of said something else?

For the record this was more of a rant than anything else

I would like your view on this
