*gots a BIG problem* ~plz help~

My best friend has been broke up her boyfriend know for almost 4 weeks and this is going to really tear me up. Her boyfriend and I have been talking on MSN and the phone. Well see we talk about there past relationship sometimes and then there was the night he had told me that he loved me a lot, it was the day after they had broke up.There still best friends My questions are

What do I do?
How do I tell my friend?
How do I tell her about our conversations?
Or should I not tell her?

What do I do? You realize you have two friends.

How do I tell my friend? You realize that you have two friends and figure out which friendship is most important to you.

How do I tell her about our conversations? If you do not tell her then you may lose both friends.

Or should I not tell her? That would be unwise since they are still best friends.

You are the third wheel in this 3 ring circus. Getting involved with someone right after they break up with somebody else, especially you friend, is not wise because they may patch things up. Then you would lose both of your friends anyway. Being honest with both friends is wise even if you lose one or both. To thine ownself be true.

Be completly honest with Both of them.
The truth Always has a way of coming out, so it's better to put it out there yourself.
And make sure they Both know your intentions.

I told my friend that her ex boyfriend is telling me all this stuff and she said that he told her that he has feelings for me but I don't really know what to do because I don't wanna ruin all our friendship if you know what I mean???

its me

What do I do? you keep it quiet fr a while
How do I tell my friend? you don't untill she has found someone, friends will be around longer then boys!
How do I tell her about our conversations? ditto
Or should I not tell her? you should tell her when YOU are ready not untill....she needs to find out from you not from anyone else, be prepared to fall out but she will be ok after a while.
