I have a very close friend (female) but I often feel the friendship is not good for me. She is great fun and I know she adores me (we go back a long way and our lives are hugely entwined and I can't imagine us ever not being in each other's lives) but she has an unpredictable, slightly erratic side that I find very hard to deal with. I know I need to take a step back from her emotionally and not let the way she is affect me, but our day to day lives are so linked. I wish I could just brush it off when she does something I find hard (like cancelling a plan or brushing me off when she's got 100 things going on), but she's so important to me that I tend to take it really personally and overreact. When she's in the right mood, we have such a lovely time and this keeps drawing me back to her even though I know it's not healthy. I feel a bit like a puppet on a string at times. It's hard to make any kind of break...partly as our lives are so entangled, but also as always pops back up (normally messaging) whenever I try and create some distance. It's really hard.
