It doesn't look right for me. She doesn't seem to take things seriously. Some girls are that way. It's kinda tough to make them understand how do a men feel because of such acts. She may not be matured enough mentally to understand what she is doing. Or maybe she doesn't know how do you feel about it or she thinks you take it cool. There will be a lot of questions you need to answer to understand the scenario well. You had a convo about it with your girl, but how serious were during your convo? were you able to express how you feel about it?
