I saw lately a beautiful young woman with selective mutism. Maybe she also thinks that she will die alone. I ´ve a man with celebrar palsy who can barely speak and walk and he is married to a healthy pretty woman. I ´ve seen another 1 meter talk young guy with many disabilities, his caregiver was actually his pretty healthy young wife. I want to say, everybody (if you are a nice person) can find a partner. Just dont use Tinder or another bullshit app. And dont look like a depressed person, be nice, you can just write with a girl for a while. If she likes your personality (and the personality is what actually matter) and is the right kind of woman, she wont mind any disability.
