Is this bitchy??

So me and my SO got in a fight and because of this, I decided I didn’t want to see him tonight (we don’t live together) because I wanted some alone time. Basically, he didn’t like that and as the fight went on, one thing led to another and he ended up saying how he thinks it’s best we break up. Out of anger, I replied back saying I didn’t want the relationship anymore anyway and this was what happened after ..

I said “stop messaging me” because I knew he would keep spamming my phone and I didn’t want that. Basically, now that I’m calmed down and not so mad anymore, I feel like telling him to stop messaging me was a bit bitchy.

Ladies, be honest!! Is what I said bitchy?
