I'd have to go along with Lilith on this case... guys are really complicated with their feelings and TRUST ME, when a guy says he's got some feelings for his ex, then thats it, youre not his first priority. I know it's hard cause you've been having such a great time but if you want an advice, my advice is to wish him good luck in the future, and if he ever thinks about you again he's welcomed to call - cause let's face it - you still got and will have feelings for him, so you don't wanna be closing all your doors.

Good luck with that, it's painful and teary nights are up ahead I'm sure because I've been through it, and loving someone more than they love you...it's hurting and somewhat humiliating...you sound like a smart girl, and I think you've already figured out what we're saying here, but, as Lilith wrote, you only need to believe in it now and act to it.

Hope that helped, and I totally feel for you and know what you're going through. if he's not 100% yours in his heart then it's really not worth it.

PS there's no use fighting for him. let him come to you if he truly loves you the way you love him.
