Another one who can't believe some of the comments supporting the DH.
Would he have been unreasonable to be pissed off/angry/embarrassed at having to come collect OP? Absolutely not, although as a 1 off occurrence most decent partners in a healthy relationship would just take it as one of those things, perhaps tease OP the next day. But to refuse to collect her and then switch off his phone, how could you think they are anything other than unreasonable???
No wonder so many relationships break up so easily if you only care for your partner in perfect circumstances, and if they do something slightly wrong all your obligations to them are cancelled. What happened to 'for better for worse?'
Those posters also seem to be missing the point that at the time the colleague called OP wasn't safe in their house - they only took her home with them as a last resort after the DH refused to come. If colleague and her DH hadn't been such decent people presumably OP would have just been left, incoherent and vulnerable in some nightclub/bar miles from home. I can't believe people expect that it was the obligation of colleagues to look after her, including driving her home the next day, but that asking the same of her own husband is too much!
Has the DH even met the colleagues? For all he knew they could be dodgy as fuck!
How anyone can think that's ok to treat someone you love, and promised to 'cherish' I don't know!
What if OP hadn't been drunk but had been spiked or was having a medical episode, both of which present the same as being pissed? The DH wasn't there, he didn't know what had happened. Does she still deserve to just be abandoned then?
