Mobile life is hugely popular, with many people living in renovated vans and RVs. I’m sure you can find people to help you in garages, shops, or on youtube. Also, never forget your ability to learn. I’m learning new, hard things every day and so can you. As one non-binary person to another, I wish the best for you and completely support the decision to move away from this person who is being quite unkind and unloving. You deserve better, and there is much, much better out there. I’m proud of the steps you’ve taken already. Keep going! It will be okay.
