Do I make a move on her

Credit to Emelvee for translating my horrible English.

My friend Sarah left her significant other after he had relations with many other women. I have long been interested in having a dating Sarah, but she has always been in a relationship. She has not shown interest in me romantically, to the point of discussing with me her interest in other men.

Recently, we dined together, but simply as friends. We were alone, but it was not a date - it was planned as a group get-together, but the others did not attend the meal. At this time, she noted that she is not prepared for a serious relationship at this time. We had an enjoyable meal, and met some of her friends later. I made an effort to socialize with her friends and not monopolize Sarah's time. It appeared that all involved had a pleasant evening. Sarah took me home and gave me a goodnight hug. She suggested that I should stay an extra day and join her at a birthday celebration. I informed her of my intend to go home instead; we live in different states.

I received a text message from Sarah later in the morning; she explained that she enjoyed having dinner with me, was glad I was able to attend, and hoped that I enjoyed the time together as well. This text message encouraged me to extend my visit another day. I joined Sarah at a club to celebrate her friend's birthday. I did not focus my attention on Sarah during the party, though I did share a couple of dances with her. I did notice another gentleman flirting with Sarah. This did not disturb me, as I had lost any hope of being more than just a "friend" to Sarah based on her previous behavior towards me. I am hopeful that my plan of playing little attention to her was successful in her developing an interest in me romantically.

At the end of the party, she drove me and my friends to a friends home. I returned to my state the next day. On the morning of my departure, I received a text message from Sarah stating "thanks for coming out… I had a great time… glad you stayed an extra day". I did not return the message. She sent another message, containing an inside joke and inquiring as to whether or not I made it home.

Over the next couple of days, she appeared to be spending a lot of time on my Facebook page. She made some jokes on my Wall. I noted that I wasn't feeling well, and she states that she hoped I would feel better. She made another joke that perhaps my leaving her area was what made me sick. She posted a comment on a very old photograph of mine, making yet another joke. Finally, I listed on Facebook that I am single, then one of our mutual friends asked what is going on - a single heart icon displayed on the screen, making it appear that I am in a relationship. Apparently this caused some confusion, as Sarah made the comment "o its okay, I thought the same thing… but it says single". She made her comment just two minutes after I posted that I am single. To me, it looks like she is stalking me via Facebook. lolomgwtfbbq.

As you might expect, I am thinking of Sarah continuously at this point. She will be in my town on business next week, and will be staying at my home for a night or two.

Do you think she is now interested in me? Her behavior with me has completely changed of late. Should I flirt with her when she visits me, and try to move in on a woman who recently exited a difficult relationship? I would want any relationship with Sarah to be meaningful and not simply something she runs to after leaving her previous relationship.
