You definitely put yourself out there a little - but you could be doing more. If you're truly looking for love, try doing more things and meeting more people. You don't have to actively look for love, you just need to stay active. Be out there a little more, and the right person will find you!
You are on a good way. Flirt could mean you guys only met or fell in love a few days or weeks ago, but that doesn't mean you can't fall in love! Flirting is something people do a lot, you see some one you like and in that case you of course you hope that person to like you too! When you get to know this person better you could be an amazing couple! My advice: Hang around them more, try and talk to them and once you achieved that: Do something fun together! If you don't want to go on a date, just ask some friends with you. Could be a lot of fun!
