If my husband came in from a works night out and a female colleague had been coming on to him all night, he would have told me and it would be the same the other way about.
Depending on how serious it was, we would have either laughed and said "Omg, s/he will be mortified on Monday" or "you should maybe avoid him/her and let your line manager know why".
The worst one for the two of us was his new manager. Not inappropriate, just mortifying. They had a "Christmas night in", so everyone brought food and drinks and it (unfortunately) started at lunchtime.
His manager got completely pissed and ended up locked in the women's toilet in a cubicle having passed out.
The other women asked my husband if he could break down the door to get her out, which he did but she was completely out of it and they had to call an ambulance.
The ambulance people got her into a wheelchair and covered her in a (white) blanket, then wheeled her through the party room which had a glitterball. This unfortunately highlighted her exit, as the glitterball made the white blanket fluorescent 😂.
She never went back to work, but her husband complained and said someone had spiked her drinks. They hadn't, she had just started drinking at mid day on an empty stomach.
I have never laughed and cringed at the same time as much as I did with this one.
My point is, that it's perfectly natural for partners to share their works night out experiences.
I have no idea why some people think the OPs husband is dodgy just because he shares stuff with his wife!
