this is me http://i349.photobucket.com/albums/q388/cshss/HPIM0554.jpg
ok ive asked a few similar questions and none of the answers helped me. i just want to know what is wrong with my dating life. im 15 and have only had 3 gf to speak of and each lasted about 3 days. im always told “just wait and play around and have fun and flirt”……yah i dont WANT to flirt i want to be serious and just have someone to you know pick me up when im down and me do the same for them. every time i find a girl i like she doesnt like me or already had a bf. im a really nice, funny, caring guy and i just need some advice. i like this exchange student from germany she is just now 17 and has the most GORGEOUS eyes. theyre hazel and i love her eyes and she had blonde hair and shes tan and has the cutest german accent and is adorable cause shes like a martian and doesnt know what hardly anything here in america is…..but theres a catch…..she has a bf…………
