14 is a rough age for anyone. They just got out of middle school, which can be absolutely brutal on the self-esteem. The teenage years are a time when it is perfectly normal to try to separate themselves from their parents, so there is a lot of "behavior" that goes along with that. It can be confusing for parents of autistic teens. Is this "normal" teenage behavior, or is it the autism speaking? It's probably a bit of both. Both my boys (non-autistic) spent ALOT of time in their rooms. They built their own computers and loved to tinker around with them and play video games for hours at a time. The only time we really spent any time with them was around the dinner table, but we
really made an effort to involve them with life skills, laundry, balancing their checkbooks, cooking a meal, auto mechanics, etc. With boys, I think they really get some satisfaction out of being "useful" and respected. So sometimes, as parents, we would create the circumstances where they could do something and then being given gratitude and props (positive reinforcement). Both are successful engineers in their fields and we are very proud of them. However, getting them there, Holy Moses!
It seemed like we were riding their butts all the time.
Some autistics are not classroom students, but if you give them a creative project, building something, doing something that makes them think and solve problems, they often thrive. The skilled trades, and there are plenty of them, and in high demand, with high salaries might be a path if the university is not for him. Frankly, right now, I would push most kids in this direction versus a university degree these days. A year or two of hands-on skilled training in any one of several fields, very little debt, and some of these jobs can yield 6-figure salaries within a few years, far better than some 4-6yr professional degrees.
As parents, I think we need to swallow that hard pill that some of our kids are not going to have spouses and children. My own boys, and one is married, but we don't expect grandchildren from either of them. This latest generation have a million and one reasons not to get married and have children. The "icing on the cake" is that as autistics, we struggle with social situations, communicating effectively, social anxieties, and we are often unable to "read" people, leaving us at a significant disadvantage. It's frustratingly painful for many of us not to have friends or a significant other. The Greek root word for "autism" is "auto" or "self", and it aptly describes our social experience, that is, being by ourself. I am married and have been with her for the better part of 38 years, but despite having many good acquaintances, I don't have any friends. I have enough mental energy for one person, and even then, I think she struggles with me at times. I make sure she goes out with her girlfriends every few weeks just to talk and socialize. We spend a lot of time together in silence. That's living with an autistic, and certainly not for everyone.
Having said that, as parents, we don't want our children living with us either, as adults, and "failing to launch". So, at 14, you have 4 years to create a good citizen of the world, good morals, a drive to succeed, self-disciplined, responsible, accountable, with some life skills to survive out there without him knocking on your door in tears at the age of 20. The clock is ticking.
