Search Results: called the wrong name

Right, this post is actually inspired by a post that @Kaneki made about someone not knowing that he didn't like them, like him, I have a similar issue and it is proving difficult to fix, please consider before suggesting methods that could hurt the other person.

There is a guy I am fiends with, for easier reading I will use names.
Andrew is the guy I am talking about and we have known each other for a long time, he has had a lot of girlfriends and always introduces them to me as well, after awhile he got into a relationship with a girl called Hannah. The relationship lasted for a while but later on it stopped.

Not long after the relationship, Hannah would message me frequently on social media and talk to me, asking if Andrew missed her, if he talks about her, what she should do as she still has feelings for him..

But things have gotten worse this year as now she messages me saying stuff like-
"Jack, you're the only one I can come to for this kind of stuff"
"You honestly are the kindest guy I know"
And others but I don't want to put loads up, but thing is, I don't want her to get the wrong idea, I find talking with her very difficult and that's because she always talks about her relationship with Andrew and will always say how I was super supportive during and after the relationship.

I don't want to be friends because it feels awkward and her personality is so different from mine that we have nothing in common and also, because she is my friends ex, it feels weird talking so casually with her :/

So when she talks to me as though she has known me all my life, it feels off and I don't know how to deal with it.
