Hi Uly,
The Russian context covers both distant and personal contact:
«Это была новость! До самой нашей свадьбы никто на работе не знал, что мы с Ольгой общались уже полгода. Ну разве что пару раз нас видели вместе, и то это были разные люди.»
Sorry for hitting you again with the same old question:
Does COMMUNICATION covers personal contact like in my snippet?

yes 👍🏼

Issue closed 🙏

To think, that was 1979...

wow!

Uly, can we say:
Tomorrow there will be 2 years since we've been talking/communicating.
?

Yes, but if you use “talking”, it sounds like you were not talking before because you were in an argument, and then you resumed talking.

Similar meaning in Rusian:
Мы с ней долго не разговаривали ( после той ужасной ссоры).

Good to know!

Uly, could you check my explanation here:
