<human>: Summarize the given text in a few sentences.

Long story: I moved around a year ago to help a close friend start a business. He's been dating this girl (Kelly) since highschool and at this point I'd call her one of my close friends. Close enough to where I go to all the family parties and eat dinner with the parents at all. She's got a younger sister (Michelle) that I always kinda liked. Michelle was dating someone (who her family hated) up until a couple months ago. As soon as she broke up, Kelly started playing matchmaker -- and apparently the interest was mutual.

I tried to get Michelle to go out once (through kelly because I didn't have her number at the time), was told she had work along with a little comment about her not being interested in dating and it having to be "fun buddies" at first. I had a formal banquet this weekend where my business partner and Kelly were both at, and I took Michelle as my date. The date went well, we danced, had some drinks, went to an after party. Michelle stayed over with my business partner (also roommate), and Kelly ended up sleeping on the couch. I'm sure I could have gotten her to sleep with me, but I didn't want to push too hard.

So, at this point, should I be ignoring the mixed signal and try to take her out for Valentines day (or other dates)? Alternatively, I could just go with the flow, and see where things end up.
