If you try to translate it, then we may be able to guess your meaning.

This is the translation according to one of my Ukranian friends: "Another one stopped texting, she must have realized that I'm not interested in her"

I need an Ukrainian native speaker who speak English good enough to translate this sentence in English. Thanks for your translation, I think I got my answer now :)

Emilia, it is not clear native speaker of which lnaguge is needed, Ukranian or English:/ I'n not a speaker of any of them, but the text is easy for a Russian. In case you need a quick answer, I think it means: "And the other doesn't write anymore. She likely just realized that I'm not interested in her :)". ('just' here means: "Likely, it is just [because of] that she realized..." - i'm just trying to give an idea of what it means.) "А другая уже не пишет. Она, наверное, просто поняла, что я в ней не заинтересован)"

This is the translation of Google Translate... I want a translation by a native speaker
