If a person really loves you and you develop more problems which cause you problems in life like walking etc. then this person still stays near you and love you.
Otherwiese this person love is a big fake and not real.
I live in a marriage since 15 years and we have known each other for about 22 years. When we met I was as anyone else know i use wheelchair 100% and live with severe pain. Ok we have had our problems but we still live together and support each other.
I don't think you have met the right person yet. Don't be afraid of dating if you want to. And don't be afraid of telling the person about your problems. Better be straight then hide things.
Wish you good luck and that you soon find the love in your life.
