talk about shitty cards

For about a year, I've kept it secret, that K's ex boyfriend M was hitting on me. Last Thursday, he did it again, and I finally told her on Saturday morning.
I contemplated and considered this decision for a whole year... and yea, i should probably have told her what happened as soon as it happened but I didn't. I let it slide cos I thought M was drunk and I didn't want their relationship to get any worse than it was already. Whatever...
This Thursday was the last straw. I ended up telling.
Somewhere between saturday morning and evening, I suppose K confronted M and I've got hate mail coming from M now, and K will not talk to me or pick up my calls. I've been told I just ruined my friendship with both of them, which to be honest I kinda saw it coming. I was really upset this morning that K would not take my calls or anything like that. I figured somewhere along the way, the storyline changed, and I've become the bad person. But after a few hours, I just couldn't care less anymore. I called multiple times and i've tried contacting her, but to no avail. This shit's been going on for about a year already, and I just don't want to deal with it anymore. I'm kinda glad the information is out there. I'm kinda glad I'm not living with this secret anymore. For all that it's worth, I'm throwing all this crap out to be sorted. I just don't want to deal with it anymore. If K doesn't want to talk, or listen, or believe what I have to say, then so be it. I'm tired of pandering, I'm tired of feeling guilty, I'm tired tired tired. As for M, I could care less what he thinks and the friendship is over. It was over by last thursday already.
