Is my Best friend trying to make me jealous?

No. I don't think she's trying to make you jealous. It's not her fault if she is prettier, richer or whatever else than you. Money doesn't buy happiness and it doesn't matter if you are ugly on the outside. Many people are ugly but have a golden heart. That what people should look at or treasure. She probably just doesnt know how to react coz her friend likes the same guy she does herself. Don't worry about it. He's just a crush. It's not love. So why are you worrying. It'll pass
