Candle flame understanding

Hello I have an issue that I’m hoping someone can help me understand. I cast my first spell which was a breakup spell but for friends, basically I cast a spell to breakup the guy I’m dating and his female friend. The reason for this is because anytime she’s around him he and I get into some sort of altercation and have even broken up twice because of her, this only happens with her not with any of his other female friends which is why I did the breakup spell on them. So long story short I found a breakup spell online, took two black candles wrote their names and birthday on each and tied it together with a cord. Then on a sheet of paper torn in half I wrote their names, birthday, and what I wanted. I then took the paper with the lady name and placed it in front of the candle with my boyfriend name then did the same for the candle with his name placing the paper with her name in front of it. I then called out their names and said the spell that I found online when I did this the candle with the lady name began to spark a little, then I said what I wrote on the papers for him and her then burned the papers. The paper for him burned faster than the paper for her, I then repeated the spell I found online again, then I cut the cord from the candles and placed the candles in two separate places. This is what's confusing me, the candle with the lady name is burning bright and high, at points it looks like the flame is blowing although there's no wind and sometimes it flickers but the flame remains bright. However the candle with his name does not flicker or blow and at one point it looked like it was going to go out the more the candle with the lady name got brighter but then it (the candle with his name) started to grow again until it was bright and steady. Sorry for the long story but my question is what does this mean for the candles? I have pictures to show what I'm talking about but I have no way to upload it so I'm hoping my description could be understood.
