You can get to know someone better by chatting, but it's friendzone stuff dude. The more you do that the more you become buddies. What you're looking for is to be with the girl in PERSON, you want her reaching for you, wanting to be around you as much as possible, and she's not going to have that same desire to be around you when she can just do that chatting stuff. Becuase that's what she does with her GIRLFRIENDS, texting back and forth and crap. And that's what you do with your GUYFRIENDS, emailing lame jokes and the cheesy stuff guys like to chat about.
What if the guy was gay? Would you feel threatened by him? No, you wouldn't. So pretend he's gay. That's what I'm saying, you just can't see him as competition. And if you don't see him that way, she's may not see him that way.
Either way, if you start putting him down, you are letting her know exactly what you DON'T want her to know, that you feel threatened by her being with him. Which makes you look insecure. Which means she puts less value on you.
You are NOT going to change her personal opinion about another guy, or girl, or whatever. Those are conclusions that she comes to on her own, about the other person, for her own reasons. All you end up doing is changing her opinion about YOU, and that would be, here's a guy who's threatened by other men.
See what I mean? It would have nothing to do with the other dude, and everything about you.
There IS no competition for you. You are the ONLY YOU. You're it. If she misses out on you, that's it. Being with you is a once in a lifetime thing. No other guy can be you, it's impossible.
This is what's meant by thinking of yourself as a the prize. Right now you're in the mindset that SHE'S the prize, and that you need to compete with other guys for her.
This is backwards. YOU are the prize. And it is in her feminine nature to compete with OTHER WOMEN for YOUR attention.
The MAN takes the lead... he knows he can ALWAYS do better. The man goes after what he wants. And for you, that's probably going to mean finding a girl who only wants to be with YOU. You give her a fair chance, you subtly let her know you're qualifying HER.
Believe me, if she likes you enough, and knows you're the prize, and that YOU KNOW YOU'RE THE PRIZE AND THAT YOU CAN DO BETTER THAN HER, she will not be talking about this other dude anymore. She'll be too worried you've found something better.
And if she doesn't, she's not worth your time, and like a man, you know you can walk away at ANY TIME.
Jealousy will eat you up if you let it. KNOW that you are the catch, a great guy with a lot going for him, and that cool girls with a great head on their shoulders will be going crazy to claim you before another girl can.
Let this sink in...If you can adopt this mentality, you won't be as jealous, and you won't be worrying what "she" (this applies to any girl) thinks of you.
