URGENT..I NEED LOVE ADVICE!?

first off im really sorry. but if he still has feelings for you go for it. get him back...find out what is so great about his dream girl....and although it may hurt him get someone to give him a reality check and that if he doesn't move on he will loose you. friends w/ b can be good but only when ur right about to hook up. don't let him use you, i know you really love him and think he would never do that to you but it seems he already has. if you are as close as you say...sit down and talk. i know it sounds scary, but there really isn't much you can do if there is another girl involved. sorry.
