Back story: dated girl for 3 years, she cheated and I was done. Took me 8 months to get back my game. Got a great job, got in great shape, have had no fear pursing women now (thanks r/seduction)

Interesting situation: moved to new city , got a roomate who is HB8 and just an all around sweet heart. We have hit it off and hung out every night and I have even been forward with her on wanting more/having a crush on her.

Plot twist: roomate is my sisters best friend

HB8 knows I dig her and continues to flirt with me. Not looking for a slam, looking to date this girl. She is talking about how her love life is stale and has a dead end date coming up. We continue to hit it off every night and stay up late chatting but I am extremely confused, never lived with a girl before. Any advice?

Tl:dr hot roomate that I don't know how to seal the deal with
