Ugh BOYS!!! why so complicated?

ok so my ex still wants me back and he asked me if i would and i told him that i didnt know that i had to think about it and so i was thinking about it and i honestly was thinking of getting back with him but yesturday we were in 6th period and i was doing my work and so i wasnt talking and he asked me and i said that it was because i was doing my work and so when i was done i started talking but he walked away and so i didnt want to talk to him and so after school he just left right after the bell and i see him go up to my sister and they were talking i was gonna go over there but i had to go talk to a friend about something and so i didnt go with them and so later on that day when i got home my parents sit me down at the table and tell me that why am i ignoring him and being mean and i asked them where they got all of this from and they said that my sister told them and that he told her that and so thanks to him i got in trouble and made me feel like if my parents like him more than me and so now my parents acusing me of liking another guy which is a really good friend to me and ugh i now i think that im seriously done with him because hes acting like if we went out for a long time when we were onl together for a month
