I have been with my husband for 6 years now (3 years married). My husband has his son everyday except sundays and Wednesdays.  When I met his son he was 4 years old. He had 'quirks' but I thought it was just because he was young and would grow out of it. When we finally got married, I felt his behavior was still a little off. He talks obsessively about a certain subject, constantly picks his nose, places objects that he finds on the floor in his mouth, cannot stand or sit still to save his life, needs an excessive amount of reminders, doesn't care about how others feel(empathy) etc. I finally told my husband that he should get him tested for autism. He pushed back but finally after 6 months he agreed. My stepson was diagnosed with very high functioning autism (Aspergers). As the years have gone by, my tolerance and patience for his son has dwindled. I know that a lot of his behavioral issues are because of his autism, but it's hard to be patient when I see him behaving 'well' when it's something he truly cares about. If I ask him to pick up his room for example, he just lays there or will pick up lego pieces 1 by 1 and take HOURS to do a simple task. My husband thinks I nag him too much and will dismiss things I say in front of my stepson. It's hard because my husband works a lot so I feel he doesn't have to deal with my stepsons behaviors all the time. I take my step son to school and pick him up. 

 My husband and I had my son 8 months ago. Since then I have grown even more frustrated of the situation. I just can't see myself dealing with his son for another 8 more years. It's made me grown to dislike my husband in a sense because he is always taking my step sons side. 

Im so unsure on what to do because I don't want my son growing up in a split family, but 85% of the time I feel mad/annoyed.
