Ive been dating since i was in grade 5, first relation was 2months. Than grade 6 i had a 6month relationship, and a week later went into a 8month one.. Grade 7, puberty hit, acne, voice cracks i hit rock bottom with girls, lost my cutie look. Grade 8, things went up had a gf for 2months, had a few girls friends, The grade 9, 2 year relationship.. This is where things got foul for me, she was a huge flirt, other disrespectful things, and cheated on me once i know of, twice ive heard about, she lied to me several times. Then, after that 2yr break up i got invole for another 2month relation, which all this girl did was flirt, sneak out with other guys/girls. Then! after this girl, grade 11 i met this girl who was a cutter/bulimic.. but appearantly as ppl say now, hottest girl in our school (shes still messed up).. She cheated on me 2 weeks into the relationship, and towards the end i found notes/scrapes of paper saying she loved this other guy, and it tore me up.. Could'a killed this guy with one hit, but didnt touch him. Now, if you managed to read all that, here i am now.. 6Month relationship with a girl who cheated on her last boyfriend, cause "she didnt feel anything for him" I believe it, the dude is annoying.. especially when hes drunk, which ive seen too often.. Anyways, after my past i bunched up all my feelings and hardships due to my last girlfriends and i constantly feel like shes going to cheat on me, and when ever shes out i just keep repeating that "she wouldnt do that to me" and try to go on with my night.. I do love this girl, she is absolutely everything i adore and she took me out of my Massive depression stage.. I do have friends to fallback on if she does cheat on me, figured id just throw that in.. But my question it, what can i do to block/erase this haunting past so i can have a healthy relationship.. Also my life isnt Cherry! i have an extra year of school cause i failed which i hate, in the town i hate, in the state i hate, around so many people i despies.. For any Input you have my gratitude.
