This is a REALLY long story... But I have major guy issues... AND I HAVE NO CLUE WHAT TO DO!?

Ok I guess to start, I'm 14 and a girl. So, last year my dad started dating a girl named Pam. My parents go divorced so to make this clear I really do like her! She is all you can hope for in that kind of situation :) Ok so last summer we went gaping with Pam in ocean city Maryland. But what my dad didn't tell me was that her two sisters were coming. And the fact that they both have boys... Billy Sue, has 3 boys Kyle 20,Dylan 16 and Kalib 15 and her other sister Tracy has 2 the one is married with kids and Damian is 15. So when I went there I was like uh oh...... Damian kept staring at me and never even said a word to me the whole time we were there. And then when he left, we were still camping and I got this text message saying I really like you! I WAS LIKE WHO THE HE'LL IS THIS! and he told me and I was like ur a stalker stop texting me! And now he's asked me about 5 times to be his gf and he's ugly and stupid! Then Dylan, the fist day we were camping he flirted with me and he's older than me so I was kinda like ewww cause I was 13 qt that time. And he kept wanting me to go walk with him and I did. He wanted me to kiss him so I told him to F off! He didn't speak to me again the whole time. So then there Kalib, the next day after the whole thing with Dylan, I came out of the bathroom and Kalib and my friend I brought mike was outside the door.and Kalib told me what a jerk Dylan is. And I said yea figured that out by myself. And Kyle got his 14 year old girlfriend pregnant. So I hung out with Kalib the whole week and I did like him and he liked me. He did everything with me! Haha like in the pool he was throwing me around and took me to a really romantic spot etc. But when we got home it turned out he's on parole for stabbing someone and he lied to me about like EVERYTHING! so now I hate him he's a jerk and I want nothing to do with him! >:( but in 2 weeks we are going camping again with all of them except for a whole week...:( I really have no clue what to do
