Please help...

Ok so alot of you know I enjoy helping others all that I can... Well I'm alot better at helping when it's online... My fiancee and his best friend are no longer speaking because my fiancee didn't pick up his phone when his friend called and now his friend is moving or moved I don't know which but he broke down and started crying tonight. so much so it scared me and I don't know how to help him....someone please help me help him, I can't stand to see him so depressed..It scares me...

All of this over not answering a phone, it must run deeper than that.

It's cuz of the kind of person his friend is. He sees me as taking away his best friend because that's how my fiancee's ex girlfriend was that's why he got so mad. It's nothing to do with my fiancee and that's why it bugs me so much because I'm not the type of person to control someone's life like that.
I will never "wonder" as you put it because there is no more to it. Like I just said, it's not even about him, it's about his friend.
Maybe now that you know that it makes things different, I'm not sure, I just felt so badly....

I would just try to talk to him about it

If that is the case this is something his friend needs to deal with, I would hope you bf has tried to discuss this with him, in the end though, it is his friends problem and only he can solve, by realizing just because it happened that way once, doesn't mean every relationship his friend is in is going to be that way.
