Tell her that you can tell something is up. That she is important to you and that she be comfortable talking to you is also important. You don't want to put her on the spot, but you also don't want to do nothing if something is wrong with a person you care about. Then tell her how she is making you feel, and that you just want to make things comfortable again.

Hopefully you smashed before you lost your best friend

Nah i do think something is up it's just she's afraid to tell me. I will get it out of her. I know how to push her buttons.

Dude, the time has come. You must procure a boombox and stand outside her window blasting an epic metal love ballad.

Don't deny that we all want to see video of you doing this.

Also, I'm a bit torn on serious advice. I would normally tell you to meet up with her ASAP and firmly tell her what you want. However, as you flipped out in jealousy, I don't think you can do this from the right point of view. Because I have a hunch your "I still want you" message would include "You must choose between me and him!", and that ain't gonna fly.

Can you see this girl, while she keeps seeing the new guy?

Expanding upon Few's advice, I'd peace-out for a bit because...

the two of you had dated for a brief period yet she still chose this other guy; she's remaining with him, obviously he serves some sort of a purpose in her life which brings me to my next point - she gets to have her cake (you and him) and eat it too so why SHOULD she make a decision to be with you and lose him in the process; any cognitive dissonance she may be experiencing you'll only add to with your presence

Leave her be, let her realize what its like not having you around - if she truly misses your energy she'll come sniffing around again, beyond any reasonable doubt. If she doesn't, well then you have your answer. Either way you'll know so clearly you stand to benefit by extricating yourself from the 'situation'.

Either that or you've already taken the other dude's advice and are standing outside her window right now whilst holding a ghetto blaster over your head blaring Cinderella's "Don't Know What You've Got (Till Its Gone)". In which case, God speed.

So she just texted me and said Creepy old friend.. LOL whatsup

How should i respond to this? im thinking of just not saying nothing but i want your guys opinions?

Personally I don't like passive aggressive, it's not how I like to operate (and I got my fair share of it from my last relationship).

I'd respond, as not responding can be construed as pouting, or just rude (really who doesn't get texts these days). I'd tell her that you feel it is a gross injustice to the two of you, and your love for each other, to continue with things as they are. You want her to explore the relationship she's currently in without providing any interference, and you're also on a quest to be the best version of yourself you can be - and for now the only clear way of doing that is for the two of you to do your own thing, apart.

If that's TRULY what you feel you need to do go for it. Authenticity is the ultimate, all the other stuff is just games and not being true to who you are. Most guys on this board are man-children mentally, that's why they get pulled off centre by women so much, they don't know who they are and therefore can't be blamed for being anything but inauthentic using techniques and routines like town jesters in hopes that some woman will fall for him (couldn't be HIM, must have been the techniques/routines, right?). These same guys will tell you to "freeze her out" or use some sort of a canned line on her to hit at her insecurities, but really don't we want to just be better people? How true are we being to self-improvement by being inauthentic with ourselves, and with the world around us?

Just be you, you've got this. You've already made your decisions, you're the decision maker, take back control of your life and shape it the way you want to. She's currently not in your game plan to becoming a better you. Don't settle for anything less than what you feel you deserve, and don't make a bigger deal about this than it is or i'll be forced to use even more cliches.
