I'm really not sure how to best handle this situation, so I would really appreciate some input from you level headed ladies!
My BFF has a habit of disappearing for weeks or months at a time. She's done it for at least as long as we've been friends. It's generally when things are stressful, busy, or new for her. It's kind of annoying, but it's her way of dealing with things, so I deal. When she's ready things fall back into our normal swing - usually she joins in again when me, BF, and her BF hang out. I should add that when we hang out without the guys, it's usually me planning our get togethers, asking her to hang out, etc.
A couple months ago she started on another one of these times, I thought nothing of it. A couple weeks into it, her BF was over at our place so I asked about her. He told me that "she is actually really mad at you. She feels like you abandoned her." My internal response was "I'm sorry, what?!" But rather than saying that out loud, I just said "oh..." and walked away.
Being that I hate to make people feel badly, I decided to contact her. She never answers her phone, so I sent her a message on FB knowing she would see it. She used FB multiple times in the following weeks and I still got no response. I ran into her BF again when he was hanging out with my BF, and he told me I should contact her. I said that I had messaged her with no response. He told me to try again. I just got in my car and left.
I decided that I didn't want to be in a one sided friendship (remember, many years of me being the one to plan and invite), and that if she wanted to talk to me, she could make the effort this time. I finished high school too long ago to deal with this BS...
A month or so has passed since that last discussion with her BF. Yesterday I get a voicemail from her like nothing ever happened. I haven't called her back yet...
edit: feel free to tell me if I'm just being a big baby!
