Taking a break comes off just as needy. Turn the tables on her - get your fill with her, have your sexual fun and then go talk to other girls. It's your mindset that needs to change, she'll pick up on that. Stop worrying about how she feels and what guys she may be talking to. Just do your own thing, dwelling on her is really the only issue here.

Now if you want to start a healthy relationship that'll blossom, then you need to sit down and have a serious discussion with her - at which point you'll realize it's time to move on probably. But hey, you're young, have fun.

Ignoring her is immature and obvious. You can focus on yourself without completely cutting communication with her. It shouldn't even be an issue, she shouldn't phase you - at least that's what you want to communicate. If you intentionally ignore her it lets her know that you care, a lot.

So, instead, just be busier. Reply less often, take longer to get back to her, be unavailable more often, when you do talk make sure you've been busy with other people so that you can bring up the fun things you've been doing without her.

Realistically if you're living a full, fun and busy life - this will be second nature. She'll pickup on this and want in on your world. If she's lucky, you'll let her in.

See, it was that easy.

Now you can say fuck it, move on. You're really, really young and there are a lot of really amazing, gorgeous women out there for you. Take what you've learned in this relationship and grow from it. It only gets much much better from here my friend.

As for her and her number, no don't delete it. Obviously you liked something about her or you wouldn't have wasted your time. If mentally that's what you need to do in order to move on, go ahead. But a mature, confident, fun guy with the world at his feet and all the options in the world - that guy wouldn't even give her the pleasure of deletion. Move on with your life and put her out of your mind.
