I think the answer is simple, like many posters have already said. Ask a shadchan or someone uninvolved to “redd” it to her!
Now, I’d like to post my own dilemma: I was about to get engaged to a boy with mild mental issues, but then he told us about his problem, and we were told by our Rav to stay away. Since you, IrFlatbush, have gone through a similar situation, can you give me some chizuk that we made the right decision? What is it like to be in a relationship with one who has mental issues?
