I agree the age in and if itself may not be the issue. It’s where he’s at in life and just as much where you are. He’s never married? Does he want to marry? Does he want kids? If so, how is this any different than FF from years ago? Seems very much the same.
Then your D - would this really bother her? Are you certain? If so, why would you even consider it?
In the end, is he potentially someone you could date? Yeah. Is he a good candidate or the right guy at the right time? I think that’s where the problem hits.
