Max, you asked how I knew your name. Spooky, isn't it? But seriously, you wrote your name in one of your posts. In parens.
Hey, you also wrote, In all honesty I think the only goal I have in mind is to win my H back. Great goal. If you follow the DB philosophy though, you are gonna need to break it down into smaller steps. Read the book it explains in great detail what that means.
Like one step might be: to leave him smiling every time I see him. That in itself will not win him back but it is one baby step. That is one concrete thing you can try. It means you have to think of funny or amusing stories so that you can share them with him when you see him. It means you have to look good and maybe figure out how to subtly flirt with him. Or maybe it means you will have to have some new hobbies so you can tell him, "guess what? I started doing belly-dancing lessons and I have a performance on saturday." a surprise is worth a smile. there are a bunch of ways to fulfill this goal.
But this is just an example. Think of your own "baby step" goals, and then work on 'em.
