A new lady joined my tennis club about 3 months ago.
She'd never played properly before (just with friends) but it was clear she had a natural ability.
Her and I have become quite good friends recently.
There's a really horrid repellent man in the class and it turns out she's been dating him for a few weeks. I was shocked to find this out as she's so lovely. I gave it the benefit of the doubt to start with
Recently she's been playing quite badly.
She confided in my last week that this awful man has been telling her how awful she is at tennis, putting her down endlessly, telling her she'll never be any good. (She was actually better than him when she joined).
The more he's been saying it, the worse her game is getting, because she's so anxious about it and her confidence is completely broken.
Two nights ago I witnessed him talking to a bunch of the other players, criticising her tennis skills, making her a total laughing stock, doing impressions of her. It went on and on relentlessly.
I'm the only person in the group who knows they're dating.
I took him to task immediately there and then, but there was only so much I could say in front of the group. She wasn't there at this point, she'd left early after a bad game.
I don't know whether to tell her what I witnessed him doing. I feel like she'd be even more hurt but she really needs to know. It had all the hallmarks of narcissism.
I also don't know whether to tell the other people in the club. People have stopped asking her to play and don't think well of her because she keeps going to pieces on the court, but I'm 100% sure it's because he's intentionally breaking her down and destroying her confidence.
