متن اصلی - هلندی - sorry onze evt date kan niet doorgaan

Hi Lein, does this mean: "I'm sorry, we can't go forward"?

CC: Lein

No
It means

I'm sorry, the date we would have had can't take place

evt means eventueel, which in this case means it wasn't set in stone but it was something that was sort of planned and to be confirmed.
A date is usually with a boyfriend / firlfriend but can also be an appointment between friends.
Hope this helps!

Thanks, Lein

Hi again Lein. I've got a new version to evaluate.
Could this be translated as:
"I'm sorry, we can't keep on seeing each other"?

CC: Lein

Mmm - no, don't think so. That implies someone ending a relationship (or the beginning of it ). In this case it is about one date they were thinking of that can't happen. To give you an idea about the tone, one possible sentence to follow this one would be 'how about meeting up next week?'
I couldn't think of a good way to phrase this one in Spanish, which is why it has been waiting for such a long time without me having a go

Hum... I'll take your answer as a bridge and do the translation myself since two versions have already been rejected. I'll send you the points, OK?

OK No points needed...
