Is it legal for a mentally handicapped person to be in a relationship with someone who isn't?

@JimFarris16 Could be the best love story lol

@DemiGod22 So you think it's okay that he asks her out?

@WomanThoughts How come?

@JimFarris16 Go to google and read about a relationships of such sort and how they mostly ended up.

@WomanThoughts Hopefully not all end up bad, my friend is mentally handicapped and has a huge crush on a woman who isn't.
