I was sick of her being two-faced and just telling me what she thought I wanted to hear all the time.
The breaking point was an incident where I let her know about an opening at my workplace. I honestly didn't think she'd want it, but she'd been complaining about wanting more money for months. She was working minimum wage and this position would be an additional $6/hr for her. So I figured I'd mention it. Again, REALLY didn't think she'd go for it.
So she texts me back SO excited. Just, "OMG, YES!!!". Asked a bunch of details about the job. Even planned logistics of getting there - asked where it was and I told her honestly that it was pretty out of th way and would be a 50min bus ride (not too uncommon in our city, her current workplace was a 35-40min ride for her) and sent her screenshots of the bus schedule. She was so hyped and on board the whole time. I told her I was completely sure I could get her the job.
So she sent in her resume and I even spruced up her cover letter for her, and she gave it the green light. After all of this I actually started to get excited about the prospect of working with her; she'd been my best friend since we were 13, but in the past year up until this point we had drifted apart a little because I was at a very rough point in my life. This job was the turning point for me, and I was excited to share that with her and spend time together again.
Anyway, the next day my boss is calling people for interviews, and I give my friend a heads up. When my boss calls her, she quickly makes an excuse about needing to check the bus schedule and ends the call, saying she'll call back if the bus works for her. Um... Ok. So I texted her asking what that was all about, and she's sticking to the excuse about the bus taking too long, even though she was fully aware of that before sending in a resume. She then proceeded to also mention that she'd rather continue to work in the same mall as our other friend (who actually ended up taking a higher paying job out of the mall no less than 3 weeks after this, and they completely drifted apart as a result).
I was just so frustrated. I didn't even care about her working there in the first place, but she acted all excited about it and made me excited too! She was only saying what she thought I wanted to hear because she doubted I actually had the pull to land her the job. She couldn't even come up with a good excuse for it. I promptly gave up after that, and quickly realized it had been a one sided friendship at that point anyway. A few weeks later she sent me a text asking what grade my younger brother was in, which I ignored, and other than that she never tried to contact me again after the whole job thing. (Even though I hadn't let on that it had pissed me off at the time - I played it completely cool, as it was over text)
Again, this was my best friend for 5+ years at that point. I was so frustrated. It really did hurt. Over a year later I texted her a picture of something that reminded me of our friendship and just received a "who's this?" in response, even though she HAD to know who it was just from the picture alone.
It's been almost two years now since the whole thing. I'm still at the same job, she has bounced around between min. wage jobs and I am making more than twice as much as her. She has also been bouncing between homes and boyfriends. I really do feel bad for her sometimes.
