Hello! Thanks for all the replies. Answers to a few questions (and some points I probably should have included in the OP, sorry for dripfeed!)
No parents/family around to help. Mine are 2+hrs away and his are 5 hrs away. And mine aren't really the sort that would help, even if my legs dropped off.
He doesn’t want to go - he is a natural worrier, which is why he is making me decide. His stress is actually making it quite stressful for me - as he is abdicating responsibility for his decision. So, if anything goes wrong, it would be my fault, not his.
The travel isn’t in his job description, in the last 5 years no one has had to go to these other two offices once. So is really a one off. They couldn’t decide if it was ok for him to go, and his boss doesn’t fancy it, so told me to decide.
I normally love it when he goes away. Without being too mean, he is useless domestically and it gives me time/a chance to catch up on some chores and relax a bit. But getting quite aware of how large and ungainly I am getting (already have agonising back pain most days) so not sure what I’ll be able to do at 34 wks. Got stuck in the bath for 15 minutes the other day because it hurt too much to winch myself out.
All of my mum’s births were premature. I was born at 33wks, so this has added an extra layer of stress.
Realistically, he’d be 24 hrs away from getting back home this time - if you factor in flights times, getting to airports, check in etc. if anything happens.
The trip would be one week, hopefully, if not maybe 10 days.
Not sure why people are calling me controlling - they’ve asked me to decide, I haven’t laid down the law or anything. This is our first baby, and for all I know, I might turn in to a Violet Beauregarde blob with legs at 34 weeks, or all pregnant women have their tits drop off at 33 weeks, and I didn’t realise so have just not factored that in my thought process.
I’m just going to tell him I don’t mind him going, then it’s up to him to decide what HE wants to do.
This has actually been really helpful - one point I didn’t consider before a PP pointed it out was that it’s not like he is massively helpful round the house, so him going away for a week won’t exact leave me in the lurch too much. And hopefully our building work will be finished by then so I’ll be able to hire a cleaner (and I’ll buy one of those grabbing sticks to pick up my pants from the floor before she comes over).
