Ohhhh gosh, girly. I can relate to this post 100%, seriously, it's like I could have written it myself:
Totally obsessed with this guy? Check.
Feeling like crap because you think he doesn't want you? Check.
No one else understands your preoccupation? Check.
Putting him on a pedestal and feeling like he is just perfect? Check.
Nobody else interested in you? Check.
Always thinking you're over him, but it comes bubbling back up every time you see him? Check.
Not wanting to be rejected again? Check.
No matter what, you CANNOT GET OVER IT? Check check check!!
The only difference is that for me, the situation is with a guy who really does seem to like me sometimes, but for whatever reason isn't really pursuing it, and I DON'T get to see him very often, but I don't want to make myself the desperate one who's calling/texting him if he's not interested, but I think he *is* interested, but then if he were interested, why is this taking so freaking long?? And of course the icing on the cake is that now because we're on summer vacation, I'm not even going to see him for like 3 months, so who knows if he'll even remember my name after that long?! But I know I'll still be as obsessed with him as ever... Ugh.
I wish I could give you some actual advice about what to do in this situation, but quite honestly, I'm in the exact same boat as you and just as confused and unsure of what the heck I should do.
I'll probably be reading over everyone else's posts on here to try to help myself, heh. But you definitely have my empathy, hon... Let me know if you ever figure out what to do about this boy, and good luck getting over him--one thing I do know is that if it doesn't work out, you WILL get over him eventually. Even though it doesn't feel like it at all now, ya just have to believe that someday it'll be "over."
