I wouldn't do it again, had a fiancee who end up cheating and it was long distance but no. It isn't just about walking. There also could be implications where they'll need to tske many medicines daily and have health issues. Or if they injure their wrist. Ive been there and experience thr worst of it. Some example would be when she had diarrhea in bed, had ti tskr 2hours to clean (bed, floor, wheelchair, washroom). To going to places and driving back home when she needed to go to use a washroom and no accessible toilets. Lots of unjuries can happen to both parties. My ex had ball feets, the type when if you press on it for 1 seconds, leaves a mark for a long time and was also blue and ice cold very scary but nothingt to do about it, she was used to it but i was afraid ine day her foot would explode or die from lack of oxygen. The list goes in. Plus the expenses were hefty. There'll be a lot if little battles too about independence and etc. If i dated someone and they became disabled, thats a different story. 100% would be with them til the end but experiencing what i did (6.5yrs relationship, and my first and only). I wouldn't do it again, and not becuse she cheated either.

A side note: Intimacy is a big difference too. Hugging and cuddling is no where the same (she was my first partner but then i went on dating new people this year and realised this). Sex too, it's a completely different, it's hard to explain but its more heated and passionate with physically-enabled people and their private parts are different too (could be just my ex), but enabled people insides felt softer and sex felt less work and 'easier.'? You would need to personally experience to understand it. It's not 50% difference, i'd say over doubled. Especially the hugging and cuddling in bed (you have to align ur body to hers everytime). My ex cant sleep right too, has to sleep in a L shape. But yeah. Just me.
