Bullied by my lover

Whats wrong with you?

My mom moved her trip day to march that way she could be here for my birthday which was on 30 of January I was finally turning 18. I wasn't to excited but I was almost done with high school so that's a plus. Prom was coming up and the idea just killed me my dad always was excited to see me go to prom and it just hurt knowing he wouldn't see me.i was walking down the halls when someone tripped me..and hell begins..
"Oh sorry didn't see you their." Stacy said with a smirk I just tried to get my purse and all my stuff that fell out.
I walked into class and the teacher stopped me "Brenda corner seat we changed seats." i nodded and headed to my seat. "mr. gilinsky" please please not next to me but since I have bad luck "next to Miss.underwood please." he headed over and sat down this is going to be a hell of a year.
..School was over and I was heading over to my jeep when someone through soda on my back "whoops it slipped sorry." I just kept walking and didn't look back it was weird that Jack didn't hit me today and it was only Stacy.i got to my car and took off my shirt I had a tank top under don't worry. I was leaving the school parking lot when someone hit the back of my car i pulled over and got off their was a huge scratch "oh no."i sighed and Jack got off the car "sorry." he looked at me didn't smirk or anything just blank face "yah whatever. I headed back to my car and was about to get in when he grabbed my wrist and pulled me back "hey I mean it I'll pay for it to get fix stop being so rude." I was shocked I thought he would hit me or something "I don't need you to fix it and really I'm being rude..you know what let this go I didn't see you, you didn't see me." he just looked at me and I got into my car and left. why is he acting like this? I called my grandpa "gramps I need a huge favor."I asked
"what's up sweetie."
"Well this person hit my car in the back and it has a huge scratch can you fix it and not tell mom.please."i begged he's the only thing I have close to a dad.
"Yes bring it to the shop I'll get the guys to work on it right away."yes" thank god for my grandpa.
I was pulling out of the drive way when jacks car pulled up.what is up with this kid today first he hit my car then tried to apologized and now what? I rolled down my window "hey I came to ask if you want me to take your car to fix it." he was being nice to nice "no I don't need you to help me! Can't you understand stop trying to be nice I don't want your kindness I have someone who can fix it for me." I drove off he was shocked and I knew I would regret what I told him.
