definition of flirt

hello, this is for me to tell my story, of my life.
i should start by telling the story of how my relationship of 2 years started. i met him from my sister's friend while we were still juniors in high school. he held a bbq at his house and thats when i officially met him. i did not speak to him but instead i gossiped with one of my girlfriends there. i did tell my sis friend that he was pretty cute and ya by the end of the night when i left, my sis friend told him that i was into him and thats when event number 2 began.
that was going out for drinks (boba) and playing pool, although we still did not actually speak to each other because we were both on the timid side. but as the sun started setting, we decided to rent movies and order pizza, it was held at my house. after we all ate pizza we decided to put in a scary movie, and to this day we still argue about who hitted on who that night. ill tell my side of the story, i believe that i was on the bed first. ( in my living room we had a bed, i know weird, but it was for when we had relatives that stayed over and didnt have a spare room ) and i was under the covers in spite of fear. and then he came over and got underthe covers with me. we flirted and then our first kiss came, he kissed me. and that was our official first kiss.
after that night i had recieved information that he had a girlfriend during through it all. so i became the "other woman" so to speak. after getting out of school the next day i decided to call him with my two older sisters to confront him about this. when we spoke, he said that he was not willingly going to break up with his girlfriend for me. and still wanted to keep this going as is since he didn't want to hurt his current gf. and it was wrong for me to let him take advantage of me as well as her. unfair to both of us.
than there was sneaking out. my sis & i snuck outta the house on a school night to meet them up. He was a senior, i was just in my third year of school, and we had chemistry. we had tons of it. it was difficult to not want to be close to him. we stayed out until 4 in the morning.
the next morning was a dreaded day, staying out late wasn't a smart move, my sis and i decided to ditch school,and called theboys to c if they wanted to tag along. my sister's friend did not attend school, so it was only my sis, the senior & i, as we picked him up (we went to different high schools) he was in awe or shock. he told me that his gf broke up with him before he was able to make his move to break up with her. she beat him to the punch, which really made him feel like he lost, i guess. a few weeks later, he asked me to be his girlfriend.
