Summary: My husband’s colleague “accidentally” spilled her drink on him at his company event. Then, she practically crawled into his lap to “help” him clean it up. I’d been watching her flirt with him all night.

She even winked at him and this was the last straw. Details: My husband’s company hosted a big event, and it was the first time I got to meet his colleagues. One of his female coworkers kept glancing at him. I brushed it off initially. Then she winked at him, and one of his friends jokingly said, “Looks like someone needs some one-on-one time!” That’s when I’d had enough. I leaned forward and said loudly, “If you’re done making eyes at my husband, perhaps wecould all enjoy a professional evening?”

The silence that followed was deafening. The colleague, Sarah (34F), turned bright red but then had the audacity to laugh it off. “Oh honey, Tom and I have been working closely together for years. We’re just comfortable with each other. No
need to be so insecure.

Some context: My husband Tom (36M)
and I (32F) have been married for 5 years. He’s a project manager at a tech company, and Sarah joined his team about two years ago. I’ve heard her name mentioned in passing, but Tom never indicated any
ISsues. Throughout the evening, noticed more
things that made my blood boil: •She kept finding reasons to touch his
arm while talking
• She brought up inside jokes from their
“late night project sessions” • She positioned herself to sit across from him at dinner, maintaining intense eye
contact • She “accidentally” spilled her drink on his lap and insisted on helping him
clean it up Tom seemed uncomfortable but didn’t say anything. When we got home, he was upset with ME, saying had embarrassed him in front of his colleagues. He claimed Sarah is “just naturally flirty” and I need to
trust him more. I told him he was being naive and that if he couldn’t see what she was doing, he was either blind or enjoying the attention. This
led to our biggest fight in years. The next morning, received a lengthy email from Sarah apologizing for any “misunderstanding” but also saying she found my behavior “territorial and unprofessional.” She CC’d Tom and his supervisor on the email Now Tom is sleeping in the guest room, claiming I’ve made his work situation awkward. His other colleagues’ wives have been texting me mixed responses – some saying they’ve noticed Sarah’s behavior before, others saying overreacted.
Please tell me if I am wrong.
