Relationships never work with me!?

Relationships really never work with me...I had a boyfriend who wanted to elope to Spain and I said no...And then another who traveled and forgot about callin me...And then another who met my talkative mom and decided never to come over again..and one a few weeks ago, who just stopped callin me...And they all ask the same thing: would u wanna have wiith me and I always say...No, I'm waitin for my big day-my weddin..so I just took a looooooon break from dating.. I'm 15 btw and a senior...to me, my education first, then other stuff...ill soon be in college and I can't let this get to me...All guys are just complete jerks to me...(not all u guys out there :D) I saw my ex today and he started to put his hand around my waist and I told him to stop and then he said I was bluffin....and he was huggin another girl the next second...ugh! maybe im too nice to them...idk wats up with me....I'm totally out of datin for another 2 years....shouls i stick to my plan...or wat can u say about this???
