Okay Ladies! (Now lets get "information")

Hey guys, so I'm in a bit of a problem here & wanted some advice. Could you help?

Last year, I started attending this new church, where I met some of the youth. (Where i befriended Breanna, Alexis, Kayce, Cayden & Justin) I was new to the whole church thing & they introduced me to this convention they go to every year in the Dallas area. The guys were all pretty crazy over "the new girl" & I started talking to one (Cayden) we were good for a while until it was time to leave a couple of months later for the convention. Long story short, we get here and Cayden is all over Alexis and tells me the second night we were there that he liked both of us, but he has alot of feelings for Alexis. I cried until I couldn't anymore, & never talked to him or her again. I was recently baptized and wanted to start off on the right foot & forgave them both almost 6 or 7 months later. (Yes it was a long grudge #judged)

Turns out, they tried to date the year before I got there and it didn't work because of her parents. Well now, a year later he reaches out to me again, saying "I didn't know what I had" or "I'm trying to be better & I only want you". I still have a soft spot for him, but I can't forget what happened last year...now it's time for the convention & he's chasing after me like I'm a dog in heat. What do I do? (I apologize for it being a book)
