Drinks with the opposite sex?

Would you be ok if your SO had drinks and dinner with a female colleague AND a couple male friends/coworkers at a brewery near work and came home at midnight wasted?

My husband runs a biz and treated a female worker, and a male coworker to dinner and drinks. Some colleagues he wanted to network with and a good friend happened to be at the same brewery where they had dinner and I guess they all ate/drank together. My husband and this female colleague walked back to work together at about 11pm since their cars were there. He texted her asking if she got him ok in which she replied “yes I did! Thank you!” My husband loved the message at about 1230pm when he was home. I’m pretty upset. He did call at about 8pm and tell me he was treating everyone to dinner after a very long day. I called around 10pm asking his whereabouts and he said still at brewery and he’ll wrap up soon and let me know when he’s coming home. He came home at midnight.

About once a week he does this usually no females though. He sees it as work and bond with coworker or whatever at his work or the brewery for a few hours and comes home drunk. He thinks I’m putting him on a short leash because I get really upset and insecure
