What We Want (vs) What We Need

This is what makes it all complicated.
I'm gonna simply give you examples of some common situations.

1. Casing does matter. Does it?
You date a sexy beautiful girl with good personality. You both likes each other so much. She likes to dine in a proper place, shop good clothes, and regularly have holidays out of town. The problem is that you're not in the situation to have or even support such lifestyle as she wanted. Yes, it's a financial problem. She keep asking out for dinner and hangout and those stuff. Seems like she barely care about your situation.
But, there is this one girl who doesn't look as hot as the one you're dating. But she's sweet and simple, even you both had the same taste in movies. You've been sharing with her about your situation and she completely understand, she even encourage you to find extra money. But you don't want her, you'll find the extra money no matter what, if you can have the hot beautiful girl why should you degrade your standard, right??

2. Miss Problems
You are a last year student of a respectable university in the country. Good grades, good financial and family stability. Nothing is really perfect though. You're girlfriend has been spending most of your energy and thoughts, not to mention the times that you could've used to wrote your final paper. From lost mobile phone, accidental car crash, money problem, family issues, guys flirting her, bla bla bla. You seem can't get rid of problems away from her. Your life has been such a mess lately, not because of your own problem, but simply because of her. You care so much for her, though you're tired for having the same problems over and over again for almost 1 year of your relationship, but you decided to hang on, though not so sure to what..

3. You've come to your 6th months relationships. Your girlfriend is a great girl, though she's apart in different town. Everything seems well, at least that's what you feel. But you've been angry to your girl, mostly just because she asked you to keep informing you what you're doing. You found it annoying, besides it's just a regular daily routines, she knows that already. You get so emotional lately and often yell at her, though she never offend you back for doing such thing to her, whom actually didn't do any mistake. You want her but you also want to have your own time, how can it be so hard for her to understand??

Been there? Or maybe you know someone who did?
Here's what I think. Casing does matter, but it's not everything. If you're not sure with what you're holding to, then it's probably doesn't even exist. You're having a relationship with a person, not a punching bag, treat her like how you want to be treated.

Mostly, when we got deep into a relationship or when we madly in love to someone, we tend to forget what we really need. We matter everything else that really doesn't matter.
Get real. Find out what you really need, and deal with it.
