<human>: I like my friends ex girlfriend. They dated for 2 and a half years. Its been 2 months since they have broken up. 

I am 18 same with the rest of the party members involved. I have been talking to her for a little while about 2 weeks. We have been hitting off. I hung out with her once and it was just so perfect and adorable. She is coming over tomorrow too.

There is a group of friends that my friend and i are part of and i dont want to lose all my friends in the group. I was just with him but didnt bring it up because i was really scared to bring it up to him. 

I am really thinking of asking her out soon but i dont want to lose my friend. What would be the best thing to do in this situation?
