Hooooo-k, slow down with the sexism there bud.
First: Girl shit, if you really cared, you'd consider something like this important enough to pay attentin and not just dismiss it, even if you don't like how she praises him.
Next: Just because he is a douche doesn't mean he has any redeeming qualities. I can be an asshole but I do have my own redeeming qualities, such as blunt honesty and the genuine, if hidden, affection for my loved ones.
Moving on: Treating people bad is bad, girls specifically, naw. It's hard to take you seriously when yoy say stuff like that.
Finally, in the long term a month/ 2 thirds of a year really don't matter in the long scheme of things. Patience is a virtue, try talking to other people, making new friends. Is the relationship between you and the "Douche" purely antagonistic? If not, try reaching out to him.
