I know someone who is on meds for depression and his wife is NOT on meds for her anxiety. They were together for about 9 years before their marriage fell apart. I would recommend him for a shidduch any day. Her, I would not. It should be more about stability and level of function then diagnosis.
Do you have any idea how many young girls these days are getting married and finding out that their husbands have addictions to all sorts of things? Wouldn’t someone stable and under treatment be better than that?
