It's a really stupid thing of him to do but I have also seen my husband - the most caring and considerate and loving man - get carried away, too, without realising that he's missed the purpose.
He got sloshed on our wedding night (threw up, had to be put to bed, though it was about 4am!) and then stayed up drinking on one of the particularly special nights of our honeymoon with the captain of our boat (while I was back at the cabin in my bridal lingerie waiting for him!!!). The captain was so wrecked the next day, he wasn't allowed to be in control of the boat 🤣
Anyway, lots of apologies and genuine regret on his part (he still feels bad about both).
We're now 16 years together, and 12 years married.
He was just a very excited bloke who got carried away in a situation that was new and exciting.
It's not happened again.
I get the hurt. I would be too (I was! Very!). Leave him to rest. Do what you can to enjoy being in freaking Mexico on a beach!!! Speak to him in the morning. Explain the hurt and disappointment. Hopefully, he'll spend the rest of your honeymoon going above and beyond to put you first and make you feel like the most important thing in his world. If that's the case, one day you'll look back on a fabulous honeymoon and laugh at his escapades on the first day.
If he doesn't... Well, that's telling of what's to come and what happens next is up to you.
