omg, I'm not sure whether to be mad, sad, or what at this point ! Okay, here's the story...probally gonna be really long, but deal with me here. There's this guy I like, David. I've known him for like...ever. He's two years older than me, but I REALLY care bout him and stuff . We're in this weird brother/sister relationship that he came up with and all. Anywayz, this weekend, my BFF, Katie, and her family brought me to the beach. Now Katie knows David and his brothers through me and she likes David's brother Danny. So we would call them every night and she'd say I could use the phone most of the time because she'd always hog the phone all to herself the night before, but instead, I'd get only about 5 minutes while she got like, 3 hours. She'd tell her sister to call me over so that Katie could use the phone (her sister told me and I KNOW it's true ). I think she said somthing to David while they were on the phone like, all night because when I got home (2 hours ago), I called David and we had a short convo, but then I had to call him back. So I did (like, 20 times ) and no one picked up. So I went online and his other brother (he has a lot of sibilings) was online, so I was like "heyy, tell David to answer his cell" and I was replied with a short "he blocked your number and dosn't want to talk to you anymore". Now all I'm saying to his bro is "why" and I KNOW he's there cause I see that stupid "... is typing"...but then it goes blank. I'm crying as I type this and I dunno if it's true or not. I just need like, answers...if possible. Help and I'll love you forever
