So just for a little background I wouldn't really call myself a pua of any sort as I have not spent much time in the community and am not too familiar with many terms. I did think this would be a great site however to ask for some advice with a chick I'm currently talking to. Here are the details:
-met this girl on tinder but we're now talking on fb and texting for about a week
-we're both college students on break and won't realistically actually have the chance to hang out until august
So this girl has asked ME to hang out multiple times when we get back. She keeps telling me how she wants to go sake bombing on date nights with frats in the fall more. I told her my frat does this often but that she has to prove to be a good sake bomber before I try to find her a date. She then says we should do some practice sake bombs when she gets back and that I won't be disappointed. I agreed but here's my problem: I have a girlfriend who I'm not just yet ready to break up with. Is there any way I can tell this new girl I'm in a relationship and still get her to hookup? I was thinking something like getting real close to making out so she really wants it and then stopping myself and being like "I'm not sure I can do this. You're an awesome person and I've had a great time getting to know you but I have a girlfriend *pause* you're making it close to impossible to stay faithful" and Gaige her reaction for what to do next.

Thanks in advance for the help guys! If I posted this in the wrong section my apologies :/

You are investing a ton of time and emotional capital on some random chick you are trying to bang on the side. Are you even attracted to your GF or having sex with her? Seem s like you need to break up with her if your investing this much effort in this random tinderr chick.

If you start getting interested in this new girl you should probably break up with your gf. You even have time to do that, right (you said you are going to meet her in august)?
Remember: there is nothing wrong with breaking up with your partner.

Otherwise, you can always try to arrange a threesome, but let me know how you'll think to do that because it looks highly unlikely to me and if you do, I'll have something to learn from you.

Stop being a little bitch and break up with your girlfriend if you're doing this. Don't be a selfish asshole and string her along because of your insecurities.

This is how an insecure woman thinks... that's why you see them relationship hop.

First you need to stop being afraid of the thought of being single... period. That's an Inner Game issue.

If you don't have the confidence that you can be a single man and find a woman to date that same day then you're using the material wrong.

Pardon me for being abrasive It's only tough love!

My 2 cents...Remember I'm 37 and dont know jack about the college scene. I do know how to treat a woman "right."

Friend zone her for now(but do not tell her you did it)...You putting her in the friend for you and allowing yourself to focus on your current GF. So you can reach down, grab your balls and make a decision on what you want. Keep things realistic, maybe even tell your GF about the situation and say "this chick wants me to set her up with a guy in my frat." It may also get her to devote more attention to you. that will defuse the GF and show you being a good honest guy about it. doing this will depend on what kind of woman you believe your GF to be. If she is a jealous wreck then it's best to just text here very very sparsely and should you get a text from her just brush it off when your with the GF. DO NOT Answer texts from other chicks when with your GF, bad idea.

Relationships, GF's and getting laid is not always about who is the hottest. At some point rather soon you will figure out that finding a great woman and banging her every day(or many times a day) is better than banging 20 women and trying to juggle them.

good luck man!
