Is it ok to cry in front of your partner?

My husband is worried about his sister I told him there's nothing to worry about she's gonna be fine he's upset over a video he watched about a girl who was similar to his sister only she was severely abused and neglected by her parents they let her melt away and die on their own couch his parents would never do that they're sweet. His sister is just like this girl not much younger she's 30 she has server autism and mental disabilities but that's normal for a disabled adult yet she's more mature than what disabled adults are. She does love little kids stuff but she also likes adult stuff too she loves horror movies and crime shows. Why would any parent make such a big deal of that there's nothing wrong with liking kid stuff as an adult I love some cartoons I don't have a disability but I do like kid shows at times even kids movies I watch your never too old for Disney or PBS or any kid stuff whether disabled or not guess her parents didn't see it that way. I can't imagine what this poor girl went through her parents wouldn't even let her go to the bathroom like WTF they just let her go on the couch who does that to their own kid disabilities or not. I watched the video with him it was really sad and disturbing why did her parents treat her this way with an autistic child she probably didn't even understand or realize what was happening to her. I'm glad my husband's parents are nice and not treat his sister that way she's more mature than most mental adults her age also she can talk she doesn't make noises or throw tantrums like a lot in her youth group do if someone has a fit she just put her music on and ignores it she's 30 but acts like she's 16 she's very mature not many autistic adults talk but she does only when she wants to other than that she is kinda shy. I told him there's no need to worry. Is it ok to cry in front of him? How can I help him feel better? Why were this girls parents so mean?
