Wew. . .long story with full of sad contents

. Well, here's my share.
The guy is serious about you, we'll that shows as how he cares about you. He traveled the world to meet you? Isn't that something BIG? To tell you the truth, guys (Not because I am a guy, but based on experience) are good at flattering women. Yet, if we cross the sea for one, we are DEAD FREAKING SERIOUS

about that girl. I did that once, but wala lang nagkakami coz of some reasons...
So, if I were you, keep the communication on, but don't pressure him too. Just do the natural thing that you normally do, and let bygone by bygone. He must have "NOT SAID ANYTHING ABOUT THE GIRL" before ka nag State, yet that doesn't mean that he is not honest nimo. It so happened that you weren't the "FORMAL GIRL-BOY" relationship at that time. Kung baga, fling-fling to nga natinood. Tehehe. . .
So, settle down and relax, and trust him. Focus to what you're doing now, and hope for the better that someday magkakuyog mo again. But, as they say, lisod ang long distance relationship. So, might as well, expect the worst to come too para dili kaayo sakit if ever something went wrong man gali.
Hope that helps.
Sam.
