exactly! the cancer guy i met also did the same thing: disappeared! we live in different cities. after having great times in his town, he said he'd come to see me in my town soon. but then that's it. after about two weeks i texted to ask if he'd really meet me, he said he'd let me know. but he's never contacted me ever! does it mean that he's not interested in me? no.
me, being an impulsive girl (and i still clearly remember that he told me he really liked me and that i got him smitten, too bad i ignored it because i just had a bad experience with a guy before him), met him again a few months after that, when i visited his town (his town is a popular tourist destination). he acted sweet and asked why i never called or texted him. i told him, why didn't HE call me? but i didn't get any clear explanation. to make the story short, he and i had a wonderful evening. and in the morning he was sooo romantic and asked if i would come back (i said "it depends" and he understood). when we said good bye, he asked me to call him sometime. which i did. he always responded, but never ever initiated the contact. it went on for more than a year (we even went on a fantastic vacation together) because i sort of enjoyed chasing him.
but it ended about 6 months ago. he said good bye. don't know what i did, but i guess it wasn't me. he told me he had trust issue (he was divorced once and his last serious girlfriend left him to marry another). oh he also honestly told me that he's been seeing other women but still couldn't find anyone who touches his heart (which means i didn't touch his heart, sigh..). but then he told me a few times that he's decided to stop womanizing, a decision that he's not taken seriously. that's the things about cancer guys: inconsistent, vulnerable, sensitive but insensitive about others' feelings. on the good side, the are caring, nurturing and a homebody.
