A few days ago I got to know a person on a social network. We had a few days of innocuous conversations on WhatsApp, but then they started becoming intrusive and imposing and didn't respect my time. After I hadn't been replying for a few hours they started telling me off and accusing me. I had enough and blocked them.
The thing is, they are disabled and obviously are having some psychological problems. Now another person which introduced themselves as their partner is writing to me that it wasn't nice of me, they have gone through so much suffering recently and I have to be understanding and all.
Given the emotional instability of my former online friend, if something happens to them, can I, in theory, become subject to legal prosecution? I didn't offend them and never said a wrong word, I just respect my time and don't want to talk to people who don't respect me. This all is very disturbing.
UPDATE: the person is from the US, and I'm from Ukraine
