I (24,M) am with this amazing, beautiful girl(24,F) for nearly 7 years. we started out as best friends but felt we needed more and here we are. I absolutely love her and the best part is we are best friends first and then 'us'. we tell each other everything, even if it's a random thought that occurred in our head and may sound stupid on many levels. now, she's working at this major firm (I'm in college) and guys hit on her despite she telling them that she has a bf. and it irritates me badly that sometimes it spoils my day. my question is - is this normal ? do you guys or girls feel the same ? how can I handle this situation ?
