So for about a year I was friends with, lets call her Bethan (the brunette), we would go out together sometimes, but the truth is I only saw her as a friend. Fast forward a bit and I get together with my now girlfriend, I'll call her Leah (the blonde). So Bethan is upset about it, she messages me still sometimes saying she is better than Leah etc. she insults her as well which makes Leah mad. And this is the current situation.
They're pretty well matched physically, I'd guess Bethan is slightly taller and Leah is slightly heavier, but neither are significant differences. Also Leah is a year older than Bethan.
I haven't seen either in a fight but I think Bethan is more aggressive but a bit uncoordinated, I can imagine her trying to fight standing up and throwing a lot of punches, but that's just a guess. My guess for Leah would be lots of hairpulling and I think she would try to get the fight on the ground.
I think there's a good chance they fight for real if the opportunity came up, but the thing is they don't even know each other, so I'm unsure how I could make it happen.
I know the pictures aren't the best, but its all I had to work with.
