To be upset partner going on holiday without me?

Chinese factories and shops are pretty gross he’s not going to have the amazing adventure that you had planned walking along the Great Wall, and on boat rides in Guilin, and partying in Hong Kong without you!
you are not being unreasonable for being sad that you’ll miss him, but you would be very very unreasonable to guilt trip him in any way for taking this opportunity. If my (imaginary) fiance tried to stop me going on a two week work trip I would seriously reconsider marrying them!

Well I don't think you are all that unreasonable, OP.
But, can't you go with him? Pay for your own flight, stay with him in his hotel room, and go exploring/sightseeing during the day while he's busy.
He might even see if he can extend the stay for a further week (paying for his own hotel if course) so you can do touristy stuff together.

I think it's possible they have done international business travel before.

My DH used to travel a lot for his job, some really nice places and always 1st class or business class. If he'd ever suggested not going because he'd have to leave me behind, I'd think he'd lost his mind. You should be pleased for him that he has this opportunity.

No one said the colleague 'can't' be away from his wife for two weeks. That's exaggerating and dramatising it. For all you know, he just has no interest in going and would prefer to stay home with family.

Is the assistant managers wife pregnant or
something? I wouldn’t expect my partner to refuse a work trip because he thought I’d be lonely. As if I’m billy no mates 😅

Absolutely this. Being this upset about being apart for TWO WEEKS is not healthy.

I don’t know anybody who would be pissed at this in real life.

You won't just be stuck here. Presumably you lead a full life that doesn't revolve entirely around your partner being present, so can find some interesting things to occupy your time. I imagine how exciting it will be when he comes back with his tales, and you have similarly interesting things to talk about.

Your title is v misleading. It is not a holiday 😂

Ok, there are bigger issues at play here. You are needy and suffer from low self-esteem.

Your partner is not doing anything wrong. You have mental health issues that need to be addressed as soon as possible.

You realise it's a business trip, not pleasure, don't you ?
Give your head a wobble, lovely.

I imagine visiting a factory in an industrial district in China might actually be quite grim.

He's not going on holiday. It's work. It's China - he's not going to be off on his own sightseeing.

Bloody hell, its only a couple of weeks!!! You are being very unreasonable.

Me too. That’s the strangest part of this story.

The only way I could imagine that is if the company tried to suggest it be a self-funded business trip.

I think you are being ridiculous - as is the colleague who cannot be away from their wife for 2 weeks. This is a chance to explore a new destination on the company dime.

But different strokes for different folks.

It's work, it's not a holiday and yes you are being unreasonable. Seeing your update and seeing you describe him as your 'whole world' is concerning - it's really not healthy and you need to have more of a life of your own if 2 weeks apart is causing you such anxiety. Do you have friends, hobbies, a social life apart from him? If not, you're putting all your eggs in one basket and it can be too clingy and needy. You may drive him away if you continue.

Exactly, being one of the few who have said they'd go could be a good thing if and when promotions are on the table!

This. This man treats you really badly.

If you see not having a conniption because your spouse is away for work as evidence of 'not liking said spouse much', I'd suggest you recalibrate your ideas about relationships.

Said gently, do you think your bereavement has a lot to do with this? Prior to losing your mum, did you feel a bit more secure in yourself?

It is normal for men and women to go solo business trips - and indeed enjoy and look forward to them. It is normal for the one left at home to miss them and look forward to their return.
Your reaction implies something deeper is going on. You feel 'left behind' and sad. In a context of bereavement that is very normal.
Please engage in bereavement support - it is so helpful and nothing to be ashamed of.

I am also surprised that everyone else said no.
"leaving wife for 2 weeks". Unpess they have small kids that's just odd reason and vwry infantilasing imho.

I get that since you lost your mum it's hard, but you have to get some independence again and maybe this will be good for you.

This is exactly it.

Only on MN!

Fine if your particular situation means you're both on the same page and never want to leave each other's side

Why do some posters keep on resorting to
lies to prove their point? At no point did I say we never leave each others side..

I said I can understand the Op being upset as I wouldn’t particularly want to be apart from my dh for two weeks. I didn’t say she should try and stop him.

In the early days of our relationship DH went on a 2 week trip to America that had already been planned - I was happy for him but also a a bit miffed bc I was madly in love, knew I’d miss him and I was also jealous bc I wanted to go! There’s nothing wrong with feeling that way - it would’ve been wrong to try and stop
him going though or make him feel guilty.

What I find strange is the attitude that in “healthy” relationships you would only be ecstatically happy to have your dp go off somewhere for two weeks and that any other emotion means you have something wrong with you or must be chained at the hip!
