If you run into a girl 10 months after seeing her at a dinner party and she is real excited to see you might?

Might she be interested. I ran into this girl I hadn't see in almost 10 months. She was real interested into why she hadn't see me in 10 months. She started dating someone else so I just stayed away. I travel a lot on business and stay real busy so I just didn't frequent where she worked at. I didn't know that she would notice. She made it very evident that she was single. She didn't mention the other guys name but said my EX. She made it evident that she was up for anything and wanted to know if she was going to Vegas on our annual trip that my friends and I go to every year at THE PALMS HOTEL & CASINO. She is very excited about it. Do you think I should hang around more often and try to treat her nice and stuff. I ran into her again the next 2 days at lunch in a row. She said we sure are running into each other again and again. She giggled and smiled and kept looking into my eyes. At dinner with our friends she would smile at me and wink at me she kind of made me nervou
