متن اصلی - آلمانی - wir sind jetzt drei monate zusammen und ich bin...

Caps missing: Wir sind jetzt drei MonateN zusammen und ich bin immernoch glücklich mit dir.

Something else is wrong. It's written in present tense and make it quite uneasy to translate.
In English it should be:

We have been together for 3 months and I am still happy with you

but it doesn't work with the German submission.

Thanks gamine

The requester is a German speaker so she have to correct the text by herself. But let's see what the German experts say

Oh, so sorry Ernst, I didn't pay attention and I edited the text!

You don't have to say sorry Franck

It should read "Wir sind jetzt drei Monate zusammen und ich bin immer noch glücklich mit dir."

Gamine, there is no "n" after "Monate" - only if you say "Wir sind seit drei Monaten zusammen...".
About the tense - it's perfectly fine the way it is now, I think the possible English translation shouldn't bother us at that stage, because the original request is in German and not in English. (anyway: in English you would have to use Present Perfect Tense)

And yeah, Francky or Bamsa or any other expert: it would be way easier if you waited for our opinion first, before editing. (yet - no offense!) I usually try to respond to this kind of requests quite fast.

Hello Heidrun! Translation request was left in stand-by, waiting for your opinion, so no damage, as it wasn't released before you checked it.

Ok. Let me just edit the text one more time, to make it perfect

edit: I just saw: it is perfect now

Hello Heidrun. Thanks for your message thanks for having explained the use of the tense to me. Helps me a lot. Now I know it for the next time. And, no problem, will wait for your opinion next time.
