I'm going to distract my friend from his girlfriend
How do you plan to do that?
I know some girls he doesn't like at all, I'm going to call them and invite them for a drink
I see you've put a lot of thought into this.  I'm not sure why, however, because friends shouldn't get in the way of the romantic relationships of their friends.  I'm sure your friend wouldn't appreciate this meddling!
We are great friends, I want him to know how I feel.
Part of being a great friend is supporting them in their relationships. Getting in the way of their relationships is mean and could ruin your friendship.
