Shadchan should suggest whatever works with their own beliefs/ values/logic/insight, not always same as what the guy asks for.
We suggest shiduchim all the time, BH. If a guy walked in and insisted a much younger age as the only option, I would probably metion to him some good therpaist to work with first.
Unresolved issues would create a difficult marriage, I wouldnt want to subject any of my girls to it. shiduchim is a responsibility.
