What should I do!!!

ok well I’m going out with this really great guy it’s only been like 5 days I don’t love him or anything because well love takes awhile to love some one. But I do like him a lot. anywho one of his female friends like him like him a lot and he doesn’t like her as anythign more than friends. and she is like really mad at me because I’m going out with me and she is like harassing me about it. I really like him but I don’t want her harrasing me all the time.
