Being "Friends" is really a double sided thing, if one doesn't fall on the same level chances are it just will not work out. I also wish to point out that not everyone uses the Friendlist in the game as a true list of "friends". But whether one does or not no one can really and should really decide which friends one have on their list.
I rather not have any name at all, than someone that pretends or is just in it for a one sided friendship.
At hand, if you don't understand why they are doing this you should just ask them calmly you get a chance, but other than that there's not much that can be done I'm afraid, I'm sure there's many other players in a game like FeralHeart to talk with. Not everyone click together however and maybe this is one of those cases.
I will go ahead and lock this however since the topic is a bit iffy.
