<human>: Give me a shortened version of the text

Thorough version: my friend and I worked at the same newspaper. A former writer came in looking for some clips. I helped. She was stubborn, rude, couldn't be wrong, and would ignore you if you had any info that challenged her points. She went on a crusade to get me fired because she felt my opinions (published in the OPINION section of the paper) weren't moral.

Anyway, my friend was put in charge of hiring, and he started sleeping with her and hired her for a research position. I quit the paper after a few weeks of tension. My friend and I didn't see each other much. He begged me to come back to the paper, but I said no.

Every single time something happened involving this girl, he took her side. Whether she was right or not doesn't matter. I never pushed it. I let him know once what I thought of her. I always backed off.

We got into it pretty bad today. I criticized an article run in the paper. It was the sort of thing the girl was saying she thought would be good to increase circulation in the paper. I thought it was terrible. It was basically gossip fodder. I lost it partway through the argument and basically accused him of hiring her solely because he slept with her. We've never fought like this before.

Reddit, please help me. It feels like he prioritizes this girl over me. With her around, I can't be happy. I can't be friends with him when she's all over his every thought. Literally every other friend we have can't stand her, but he'll defend her to the death. I can't make him choose between us, obviously.

Do I cut my losses and end the friendship? I'm not a good friend with her involved, and this sore spot is only going to get bigger. He's still one of my best friends, and I don't want to lose him. But at this point I don't know how to function with her in the equation. Is there a way to be friends with him even though I can't deal with this girl at all?
<bot>: Friend prioritizes girl he's sleeping with over me to the point that it's hurting our relationship. I have already bitched him out about it once. Is there anything I can do to save our friendship?
