It's past time for you to move out, and it sounds like your folks might have some problems. Some parents don't want their kids to go, since they would then have to deal only with each other and work through some of the "what do I do with myself now that the kids are gone?" issues. You have to do it sometime, so go ahead and create your own life now!
What's the problem? Many move out at 18.
Not weird at all. I too prefer to live alone. I have enough of my own crap to deal with... do not need anyone elses!
If you move against patents wishes or not is ultimately up to you. It is time for you to grow up & live your own life. Any parent that begrudge you for that ha some separation issues. They will have to learn to let go eventually.
Good for you. I moved out at age 18.
Yes, it is time and it sounds like you can afford it
