So i have been with this girl for about 6 years now. First 4 were good, we had our arguements here and there but we got over it and life went on, About 2 years ago her teenage son came to live with us (he is 16 now) I have tried to get along with him but i just cant. He has issues i think. He will not leave the house to go out and meet other kids. He comes home from school and goes straight to his room to put his phone to his face and play games. Anyways, There have been a few incidents with him that i just cant understand. 1- One day his mother was working late so i cooked supper she asked me to make sure he eats his vegetables so i put some on his plate and told him to make sure he eats them as per requested by his mother. Out of the blue he starts crying full out, tears, sobbing the works. I was dumbfounded. I asked what his issue was and he ignored me (for 3 days) and i get shit for making him cry. To this day i still dont know why he acted like that. Another time i saw some kids in the area his age playing basketball (which I know he loves to play) so i told him to go out and introduce himself and ask to play, try and make some friends. Instead he goes to his mom who is in the garden and starts the full out waterworks again, says he hates me then she gets mad and tells me its not right to tell him to go outside if he doesn't want to which starts an arguement with us because I am the bad guy for wanting him to have a social life. Think i can count on my 2 hands the amount of times he has left the house (only to go to hang out with himself. There are a bunch more issues but i dont feel like writing a novel So she say she will raise her own son her way (More or less saying that my rules dont mean shit) her son and i dont even talk to each other and the tension is beating up on our relationship. But her son just cant do anything wrong in her eyes no matter what i say. Should i tell them to shape up or ship out?
