lol!! We all have been there...

This is the part when you make him overhear you talking about your ex and all his issues. It's called payback. Hang in there OP.

Overly needy people are so annoying! It was rude of your ex but YDI

How is it confusing?

Asshole ! You need revenge ;)

He's a dick

Wow, what an ass. Looks like you're well rid of this creep.

Or maybe OP's ex could have hauled up his balls and talked to her one on one instead of publicly humiliating her (even if she was the only one aware of it). It was an immature shit move on his part. She's better off finding someone who can be open with her about any issues in the relationship. A relationship is a team effort, OP's ex didn't seem to understand that concept. Plus the little shit went and made an effort to hurt her and make their working dynamic uncomfortable. Honestly, what a piece of shit. OP, you honestly dodged a bullet. Good luck to the other woman, she now gets to deal with his crap.

Well, I do believe it's because he's explaining it in front of her to OTHER people instead of in private and exclusively to OP. I'm sure if you think real hard on that one, you might understand the problem.

It doesn't matter whether or not she was needy. He shouldn't have been talking about her like that in front of her coworkers. He should've explained why he wanted to break up when he broke up with her instead of having her find out that way. That is why he's a douche.
