How do you deal with people with such strong personalities?

One of my good friends - She has a strong personality (I don't mind) but when it comes to pinpointing down the problem and talking bout feelings with her or per se personal things - I have kinda have to unattached my emotions/feelings when talking to her.

I noticed if I don't do that - she wouldn't understand what I'm saying to her even if it's direct with emotions attach...

So it has to be direct/emotions unattached.. I find it difficult - Just cause' I'm not used to doing so.. Is there any other way?
