"friends"

I think this title sums it up. I am slightly confused right at this moment about someone I considered a great friend (not talking about you, BFG-lol!) who won't answer my phone calls and hasn't called me back. She is someone I care about in great detail and I am feeling hurt, especially when someone else asked me if we are fighting. I mean what the fuck?? I am way too old for this shit to bother me, but it still does! This is not the first time we have had a misunderstanding and I would HOPE she realized that it always gets better after we talk about it. I guess not! I am not sure I can take this kind of friendship anymore- don't gush to me about how you miss me and we need to hang out more, then ignore me and act like I did something wrong when I haven't! I am very mad right now but I don't want to dwell on it, mainly b/c I am in the dark and I don't want to feel any worse about this than I do. Should I get out of this so-called friendship?????????
