im in grade 11 %26amp; i really like this guy , his names tyler . hes supposed to be graduated but has to go back next year for another year because he failed all of his classes .. %26amp; he cant get into a good college because his grades are soo bad .. %26amp; he has a pretty negative outlook on his future %26amp; his life , he once said to me " i dont care if im a bum or have little money as long as i have enough to get high %26amp; eat %26amp; do everything i need to do , i could work at mcdonalds or do something like that i dont need a career " see , i try to help him figure his life out even though im 2 years younger than him i know alot about how the world works %26amp; the world in general , im pretty smart . i preach to him all the time , i have faith in god so i thought maybe trying to push my beliefs on him would make him better %26amp; change how he thinks about things but hes stubborn , i really like him but i dont want to commit to someone unless i can see myself with them for a really long time or the rest of my life . because ive been hurt way too much %26amp; i dont like silly little hookups or nothing like that , ive been there done that now its time to be real %26amp; grow up ! i kind of think like an adult %26amp; its been like this my whole life basically . so if we were together , would be still live with his parents , would he find a job, all of these things scare me %26amp; make me not want to be with him because i dont see him going anywhere in life.. %26amp; i do try to help him as much as i can you know, to get him on the right track but i just dont know what to do , should i stay or should i go .I like this guy alot but i dont know what to do?
