For many guys, love isn't the first priority. Maybe your parents are against her. Maybe you have education or work to worry about. Maybe you have money problems.
Why should it stop you, though?!
Think about it. If you are in love, as in REAL TRUE LOVE, why not risk everything for it?! If you truly love a girl, chase her with all your might. If you and your girlfriend are in love, do everything to keep her. If the woman you love just left you, win her back.
Excuses are for the weak, for losers who are afraid of rejection.
If your love is the real deal, give it your all. Who knows, what if you never experience the same thing again? What if you can never find a girl who makes you as happy as she does, what if you can't find a girl who you laugh with as hard as you do with her, what if you never meet another girl who is as talented and smart as she is?
I reinforce again, if you really like her, go for it. Don't let excuses and priorities stop you.
Would you rather be homeless but with someone who you truly love, who will entertain you and interest you no matter where you are, or would you rather be a lonely workaholic, with a huge empty cold mansion with no one to share it with?
No sane person would prefer the mansion. Why would you choose lonely over love?!
If you have never properly thought of it before, think about it. True love should be worth risking everything.
