Last year i had to switch schools which was ok, but when i got to the new school they changed my classes around, i found an awesome class with this awesome girl really attactive,smart,funny, respectful,careing and on the second day before school let out her boyfriend dumped her, she was crying and i was there for her and i walked her to her bus and she took my hat with her and gave it back the next day,i really like her so when summer came around i would talk with her all the time, her and her boyfriend are on and off but he treats her like shit he sleeps around with other women and makes sure she finds out,and she always comes texting me when he does and we talk on the phone, well the last time he did that to her i ended up punching him in the face and then she gave me a hug and grabed my hand and we walked off, well her and her boyfriend ended up getting back together and then they brake up again, but this time i ask her to hangout at friendly shopping cernter and we spent the whole day togeter, it was perfect we held hands have our phones off and just talked with each other..... well later on that night i sign in Facebook and she was back together with her boyfriend and i guess she told him about the day me and her spent together and now he has friends that always spys on me and her converts and he takes her phone and reads the text messages, ive tryed to hangout with her but she never comes anymore and hardly ever texts, and she keeps saying its her boyfriends fault which i dont dout,but now im getting picked on because of it...i really like her but after all of that im not sure what to do, will you please give me some advice
