Is that normal?

I just broke up with my girlfriend and I feel lighter, we were together for 5 years and I have moved away to another country, in the beginning it was fine we were exchanging texts and phone calls, but with time it became less and less, from time to time I would ask about her, how she feels what is going on with her, in last two months she started a streaming to just talk to people and not feel lonely, I was joining the streams it was just normal talking about Caltural stuff and daily issues at work, until one day someone asked her on the stream if she had a boyfriend and she replied “I’m sigle for now”, she knew I was watching that and I was so shocked and I texted her “Wow” after that I just broke up with her and told her you could have talked to me about it at least, but since you did it this way I broke up with her and she kept saying that I’m not talking to her bla bla ..

Anyways I feel I did the right thing .. thoughts?
