As a guy, I can tell u, one mistake lots of girls make, is if a guy sweep u off ur feet, he like u. I can tell u, if a guy, is sweeping u off ur feet, he is not taking this relationship seriously, he is just looking for a casual relationship or he is just joking around with you.
Why? Because, been romantic and sweeping a girl off her feet, actually require quite a bit of work, if you are just having a bit of fun, you only need to be romantic once or twice a week, for a few hours, to maintain a romantic relationship, that is easy. But if you are talking about getting married, having to be romantic 24/7 is very exhausting and it is simply not a practical relationship. Not men, who is even half intelligent, would enter a serious relationship, been romantic, at most they be romantic during valentine day or wedding anniversary, if they are an old couple been married for a long time.
So, at least now u know a pit fall, a lot of girls fall into. Lots of time, guys are just kidding around with a girl, with romantic gesture and the girl turns out thinking he like her a lot and then...awkward
